We’re being asked to determine the empirical formula of a compound given the mass of K, C, and O.
Recall that the empirical formula is the simplest whole-number ratio formula of a compound.
For this problem, we need to do the following steps:
Step 1: Calculate the moles of K, C, and O in the compound.
Step 2: Determine the lowest whole number ratio of K, C, and O to get the empirical formula.
Calculate the empirical formula of each compound from the percent composition.
2.82 g of K, 0.870 g of C, and 2.31 g of O
