Dec 27, 2019 · For example, consider a covalent compound whose empirical formula is determined to be CH 2 O. The empirical formula mass for this compound is approximately 30 amu (the sum of 12 amu for one C atom, 2 amu for two H atoms, and 16 amu for one O atom). The molecular formula is then obtained by multiplying each subscript in the empirical formula by n, as shown by the generic empirical formula A x B y: For example, consider a covalent compound whose empirical formula is determined to be CH 2 O.
