Let's say your vinegar is 5% v/v, you've got 5ml acetic acid per 100ml vinegar. Approximate this to 5g, it's 83mmol. A 1:1 mix with sodium bicarbonate would require 7g (per 100ml). Using more vinegar would make the reaction faster, but you'd have more gas dissolve.
And it does depend upon the acid content of the vinegar of course.

If your vinegar is 5% it won't be 1:1. You'd need to measure these things in some way, but you'd be after about 10 times the weight of vinegar, maybe 10 x vol, but it's hard to say with powders. L
