what is the empirical formula of a compound composed of 3.25% hydrogen, 19.36% carbon, and 77.39% oxygen? by mass
(See answer below)
Need to use the molar weights and assume there is 100g, just to make it easy.
3.25 g of Hydrogen (1 mole H / 1.008 g H) = 3.22
19.36 g of C (1 mole C / 12.01 g C) = 1.61
77.39 g of O (1 mole O / ...
