Please do I likely got it wrong but I know that it is not 3% and in fact .03%.... I thought the 100^-1 is .01 so just move the decimals over 2 times.  so from 3.26g you get 0.326 and then (/100) = 0.000326 or 0.0326%. I've seen this a lot with tiny mol and shit like that where they do ^ -4 ^ -6 and it gets annoying to try to calculate/convert to macro calculations since I wouldn't try to prepare 1ml with fractions of a mg of a product.
