1. All you need is the molecular mass of the compound and the atomic mass of Potassium, from which you find Potassium Gluconate is 16.65% Potassium by mass, and using dimensional analysis one finds you need 21g Potassium Gloconate to get 3.5g Potassium.

2. Yes - many metals like iron and potassium are absorbed in ionic form, so they will be in compounds like Ferrous Sulfate and Potassium Gluconate.

In addition to adjusting for percent weight, we'll each have to do individual adjustments for age, gender, mass. Has anyone found dietary recomendations listed by kilogram (ex. 0.11g/kg body weight for males, which I just made up based on the general recommendation and an average male body weight)
