Adding 100mg/ml nic to 0mg juice

[Tashanwrn]

I'm needing some help on adding nicotine to 0mg juice. I only have iPads and iPhones and cannot download any of the calculators, and if I did I'm not sure what numbers to put where! Can someone help me please! I'm needing to add 100mg/ml 50-50% nicotine to a 0mg juice. I have 60ml of the juice. How many ml's of the nic do I add to get 9mg???

I just did almost exactly that, just yesterday! Only I was mixing to 6mg instead of 9. See this thread for my experience and some tips.

How many ml's of the nic do I add to get 9mg???

Settle in, it's algebra time -- hope you like word problems!

"Tashanwrn has 60ml of 0mg/ml e-juice. What amount of 100mg nic base should s/he add so that the resulting mixture is 9mg/ml?"

We want to add "x" amount of nic base, so that "x * 100" (the amount in mg of nicotine in the added liquid) is equal to "9 * (x + 60)" (nine mg/ml times the number of ml's in the final mix which, itself, is 60 plus the amount to be added). Now we have our equation, which we can solve for x:

100x = 9(x+60)

Expand the parentheses:
100x = 9x + 540

Combine like terms (means "get the x's all on one side, all by themselves"):
100x - 9x = 9x + 540 - 9x <-- (The 9x's cancel each other out on the right, leaving only 540.)
91x = 540

Now just divide by 91 for the value of x:
91x / 91 = 541 / 91 <-- (The 91's cancel each other out on the left, leaving only x.)
x = ~5.934065...

You should add roughly 5.93ml. Now, let's check our work:

5.93ml * 100mg/ml = 593mg nicotine
60ml + 5.93ml = 65.93ml final mix.

593mg / 65.93ml = ~8.99mg/ml

If you just wanted to cheat and call it "six," then you would have:

600mg / 66ml = ~9.09mg/ml, which you might still consider "close enough."

5.4ml i think.

I hated Algebra, but I could do it! In nursing school I was the dosage calculations queen! Lol! I think I was over thinking it and so scared that I'd mess up the last bit of my all time fav juice!

Forget all the algebra. 60ml of juice with 100mg/ml base. Simply multiply the juice amount of 60ml times the nic desired 9mg in your case and you get 540.0

Now since you have a nice 100ml base which makes the math even easier. Just move the decimal place over 2 spots to the left and you have 5.40ml of nic base required for making it 9mg juice in a 60ml bottle. Using 100ml base makes it super easy to calculate, well all the ways are easy really if you know them

You could also say 60/100 = 0.6 and then multiply that times your desired 9mg and what do you get.... 5.4ml

CajunCloud, your method works, and is the one I use, and why I like 100mg juice, but it ONLY works if he is trying to make 60ml of final juice. He will have to waste a little over 5ml of his 0mg base in order to do that.

The algebra above is required if you want to use all 60ml of the base juice, as the OP surely does. If he adds 5.4ml of nic to 60ml of juice, then he ends up with 5.4/65.4 = 8.2mg or about 8% less than his desired strength.

Forget all the algebra. 60ml of juice with 100mg/ml base. Simply multiply the juice amount of 60ml times the nic desired 9mg in your case and you get 540.0

That works, if you're mixing for a target amount of 60ml. But OP won't have 60ml of juice, she'll have the 60ml that she started with, plus however much nic base she adds to reach the target strength. Your way yields 540mg of nicotine in 65.4ml of juice, for a strength of only about 8.25mg/ml. My way (the right way) yields 8.99mg/ml, which is a lot closer to the desired 9mg/ml, and could also be made even more accurate by mixing a larger batch and/or using more precise measuring equipment.

By the way, what you're doing is still algebra, it's just sloppy and incorrect algebra. Is it easier than doing it the right way? Perhaps, slightly. But since it doesn't even give the right answer, it's kind of a moot point. I suppose if you're okay with nearly a 10% error in your nic level, then go ahead and cut your corners, but if you're interested in yielding accurate results, then the right way is not that much harder...

I was just using the base number of 60. Sure it all depends on exactly where they nic base is in that 60ml I was just doing the simple math way. I defy anyone to tell me in a blind test which juice has .75mg more or less nic then a 9mg standard. Guys I was just trying to keep it simple for simplicity sake.

With over 10 years in Pharmaceutical manufacturing I know a thing or two about calculating yields precisely and using specific gravities of ingredients by weight etc. I've also got an Engineering Degree so the math is not so much a problem either for me. If this way isn't exact enough being a whole .75% under the target yield of 9mg then add another .5ml of nic base and call it a day. Even in your calculations above bwh79 you said "600mg / 66ml = ~9.09mg/ml, which you might still consider "close enough."" But he wants 9mg not 9.09mg, like I said I've got $100 bill for anyone who can discern the different in even .5mg of nic. LOL

Weight as you want, do the math however you want, dispense however you want. If you like it that is all that matters. Just make sure you don't OD yourself on nic!

Mind Blown? That is simple and easy Algebra - I'm not trying to be a butthole either. Further if I asked a nurse at a hospital to figure this question out and couldn't come back at me with the right answer, again not trying to be a butthole here, within five minutes it would scare me. And I'm truly sorry if I upset anyone by what I wrote.

Well, I get it, but it doesn't necessarily need to be stated.

I'm a 50 something technical writer and have not recently used algebra, as many here do not on a daily basis so I had to carefully follow the equations posted above for it to make sense. I learned it and know it, just haven't used it in years.

I'm guessing you are much younger, and use this stuff often (maybe not). I do know that my 18 year-old neice is a genius compared to me. She's taking chemistry and microbiology and took the calculus I had at college in highschool. Things have changed.

So yeah, it's basic, but generational factors come into play. We didn't NEED a lot of that stuff to compete for good jobs. The currnet generation absolutely does.

Are you talking about 0mg pre made vendor juice ?

 

[mattiem]

For my own purposes since I just get close to the stated strength of the nic. For me, if it is close it works for me. I can't taste or tell the difference between say, 10mg or 11mg nic. I just use this formula.

A= total amount of juice, in ml, that you want to make.
B= number of mg/ml of nicotine that you want in the final juice.
C= number of mg/ml of nicotine in your nicotine base.

Multiply A times B, then divide by C. That will yield the number of ml of nicotine base to use.

 

[Bunnykiller]

I would say about 7 ml.... of 100nic base

you need to consider the total volume after the nic is added....

this is the easiest method to use......

some people have a knack for math.... others dont. Ive worked with "math geniuses" that would have an impossible time with installing a ceiling fan.... come on its just a bunch of wires and screws....

and is the nic base truly at 100mg/ml? what if its 98.7 or 101.3??

Hi Tasha! You can use Steam Engine, the last tab will do e liquid calculations. I have an iPhone and I got it to work the other day...
