AI Generated Solution

To determine the empirical and molecular formulas of compound A based on its percentage composition, we can follow these steps: ### Step 1: Assume a total mass Assume a total mass of 100 grams for the compound. This makes it easy to convert percentage composition directly to grams: - Carbon (C): 26.7 g - Oxygen (O): 71.1 g - Hydrogen (H): 2.2 g ...
