Mixing Nicotine prep liquid into already mixed 30ml 0% Juice

[Spiderpig]

Hi,

I have about 30 bottles of 30ml already mixed, various flavour cloud chasing juice, the problem is that the nicotine is Zero and I'm looking to mix nicotine prep liquid to make them 6mg nicotine strength, the nicotine prep liquid is 7.2% potency and having a small brain I'm unsure how much to add to the 30ml cloud chaser juice.

Could anyone offer any advice for a struggling vaper, I have tried the apps to work it out but you may as well ask me to fly a rocket.

I look forward to any advice at all please,

Cheers Sp

Okay, so you have 72 mg nic base and you want to make 6 mg vapeable liquid? That means you're going to want your nic to constitute about 8.3% of your final liquid. 8.3% of 30 ml is 2.5 ml.

Superb, Thanks so much for that, you're a star

Have a great Christmas

Wouldn't this be a bit low since the 30ml portions are already measured out according to OP?
27.5ml + 2.5ml @ 72mg = 30.0ml @ 6mg
30.0ml + 2.5ml @ 72mg = 32.5ml @ 5.5mg 7.5% low <-- would OP notice? Would the 30ml bottle hold the overfill?
30.0ml + 2.6ml @ 72mg = 32.6ml @ 6.2mg 3.25% high <-- could OP measure in .1ml resolution?

Perhaps OP could pull 2.5ml out of each 30mg bottle and add the 2.5ml @ 72mg to get the precise ratio as you describe. S/he'd get 2 more bottles with the pulled off "bonus" juice.

Corrections and comments welcomed. I'm here to learn.

You're entirely correct - I used the rough calculation to dilute his nic down into 30 ml, but if he wants to make 32.5 ml (or more like 32.55 ml), he'd be spot on taking the finished liquid and adding to get to precisely 6.0.
