To determine the empirical formula of the compound containing potassium (K), chromium (Cr), and oxygen (O), we can follow these steps: ### Step 1: Calculate the percentage of oxygen The total percentage of the compound is 100%. To find the percentage of oxygen, we subtract the percentages of potassium and chromium from 100%. \[ \text{Percentage of O} = 100\% - (\text{Percentage of K} + \text{Percentage of Cr}) \] ...
