Step 1: 62.1% C, 5.21% H, 12.1% N, and the remainder O by mass. Recall that mass percent is given by:
% O = 20.59%
Assuming we have 100 g of the compound, this means we have 62.1 g C, 5.21 g H, 12.1 g N, and 20.59 g O.
Determine the empirical formulas of the compounds with the following compositions by mass.
62.1% C, 5.21% H, 12.1% N, and the remainder O
