7 ml will take you to 9.3 mg/ml, which should be close enough. It's 6.6 ml if you want to be more precise.
Here's the formula:
Nicotine base to add =
[volume of lower concentration juice * (final concentration - initial concentration)] ÷ (nicotine base concentration - final concentration)
which is...
[100 ml * (9 mg/ml - 3 mg/ml)] ÷ (100 mg/ml - 9 mg/ml)
or
600 mg ÷ 91 mg/ml = 6.6 ml
No he does not have 300mg! He has 100ml of 3mg and wants to add an additional 6mg to bring the 100ml up to 9mg. 6ml of 100mg nic base will bring him close enough.if your 100ml bottle is full it has 300mgs of nic. you want to bring the sum to 900mg/100ml. naturally by adding liquid your total ml's will change, but still...
as the ppl in the Shiniytis thread answered:
if you add 6mls of your 100mg/ml nic base that means you'll add 600mg nic and have a total of 900mg nic / 106mls of total liquid. which comes to roughly 8.5mg/ml nic.
if you add 6.5ml of your nic base you'll be closer: you'll be adding 650mg to make a total of 950mg / 106.5ml of total juice. which makes: 8.9201877934272300469483568075117 mg/ml.
hope your bottle has more space in it or you have a larger one.
if not you could take some out and vape it. take out 6mls of the original juice and add 6mls of the 100mg nic instead. you'll have a total of 8.82mg/ml
this is all freebase nic? i know many can DL it, but that'd hurt my throat. mtl i can do higher but not much with freebase nic, i couldn't do 12mg for instance.

bananas.. i really miss math... couldn't think of a complete formula directly,, did each step by hand. to calculate how much to reduce from the 100bottle i kept subtracting 3mg/ml and adding one 100mg/ml to get the total,,,
replace 6ml you'll get 8.82
replace 7ml you'll get 9.79
