Empirical and Molecular Formulas

Empirical and Molecular Formulas. Review. We learned how to calculate the molar mass of compounds. Calculate the molar mass of Ca(CN) 2 . 1 x Ca = 1 x 40.08 g/mol = 40.08 g/mol 2 x C = 2 x 12.01 g/mol = 24.02 g/mol 2 x N = 2 x 14.01 g/mol = 28.02 g/mol TOTAL = 92.12 g/mol. Review.
