Math Question

[purelyscientific]

I have 15mL 24mg at 80/20 at 25% juice from a vendor. The vendor allows for extra flavoring to be added, the normal flavoring is 15%. So I decided it would be good to get extra then just cut it down to make the juice last longer.

My question- What do I have to add to get it to 22mg 80/20 at 15% flavor?

15%/25% = 60/100 = 3/5

Well, you can achieve the 80/20 PG/VG and the desired strength of 22 mg nic. But the new flavoring percent would be around 20%.

I used the ejuicemeup calculator to help with this to make 15ml:

13.75 ml of your 24 mg flavored nic juice
1 ml PG
0.25 ml VG

This would make 15 ml of 22 mg juice.

Here's how I calculated the flavoring:

13.75ml/15ml X 0.22 = 0.201 (or 20%)


Edited to Add: You can get closer to your desired flavoring, but only by lowering the final nic strength. Unless you also want to add more nic, of course.

I want to use ALL of the juice.

If it helps any I planned to add a flavorless juice with nicotine. I just need to know what mg I need to mix the juice at and how much of it to add.

 

[purelyscientific]

The nicotine strength is not a big issue.
To simplify my question- How much unflavored 80/20 juice must I add to the vendor juice I bought to bring it down to 15% flavoring?

You would have to add 10 ml to your original 15 ml to equal 25 ml with flavoring now at 15%.

Here's how I figured this:
25% of your 15 ml solution is flavoring or 3.75 ml.
3.75 ml = 15% of 25 ml (divide 3.75 by 15% to solve for the total volume)

Thanks GrannyM, that's just the answer I was looking for. I will just make the 10mL at 20mg and the result after mixing will be close to 22mg.

You're most welcome. Good luck with your mix.

Sorry, guess I misunderstood your question. But Granny got it.
