# Problem: Determine the empirical formulas of the compounds with the following compositions by mass.55.3% K, 14.6% P, and 30.1% O

###### FREE Expert Solution

Step 1: 55.3% K, 14.6% P, and 30.1% O by mass. Recall that mass percent is given by:

Assuming we have 100 g of the compound, this means we have 55.3 g K, 14.6 g P, and 30.1 g O.
