Nicotine dillution

[mamamiaw]

Dear All,
Recently i was given a 100ml of 250mg PG based nicotine, but i rather have it as 100mg. may i know if anyone familiar with the calculation of the dilution?
Simply just want it to step it down to 100mg/ml with PG.

Thank you in advance

Yes, you can use a Pearson Square to calculate this.

Or you can just recognize that 100mL of 250mg/mL nic in PG is 25,000 mg of nic. If 25,000mg of nic was contained in a volume of 250mL then the concentration would be 100mg/mL. So add 150mL of PG.

Thank you for the answer
Can i safely assume that it's 1:1.5 dilution?
Meaning that 1ml of 250mg + 1.5ml of PG = 100mg 1ml nicotine.

So in my case of 100ml of 250mg, diluting it to 100mg will resulting of 250ml of 100mg ?

Thank you

I’m liking the “or” myself. Wikipedia doesn’t seem to even HAVE a notation for Pearson squares. Apparently they’re too complicated or something.

I discovered the Pearson square in winemaking. It's commonly used for blending. The unit doesn't matter, so substitute mg for ABV.

You've got it. But you meant to say "1ml of 250mg + 1.5ml of PG = 100mg 2.5ml nicotine".

Ah, yes, sorry
It's supposed to be 2.5ml or 250ml in my case of 100ml 250mg

Thank you very much!
