To find the empirical formula, convert the masses to moles: - Calcium: 0.910 g / 40.08 g/mol = 0.0227 mol - Nitrogen: 0.636 g / 14.01 g/mol = 0.0454 mol - Oxygen: 1.453 g / 16.00 g/mol = 0.0908 mol Divide each by the smallest number of moles (0.0227 mol): - Calcium: 0.0227 / 0.0227 = 1 - Nitrogen: 0.0454 / 0.0227 = 2 - Oxygen: 0.0908 / 0.0227 = 4 The empirical formula is CaN₂O₄.
