May 12, 2010 · Answers. The molar mass (formula weight) for that formula, using the atomic weights from the periodic table, is C (10 x 12.0) + H (16 x 1.0) + N (5 x 14.0) + P (3 x 31.0) + O (13 x 16.0) = 507, which equals the formula weight of 507. So the empirical formula and the molecular formula are the same: C10 H16 N5 P3 O13.
