Finding molecular formula from molar mass
WebBy mass, since Hg is heavier the percentages are: Hg: 1 mol × 200.59 g/mol = 200.59 g Cl: 2 mol × 35.45 g/mol = 70.90 g HgCl₂: 1 mol × 271.49 g/mol = 271.49 g Thus, by mass: Hg: 200.59 g / 271.49 g = 0.7388 Cl: 70.90 g / 271.49 g = 0.2612 So, by mass HgCl₂ is 73.88% Hg and 26.12% Cl.
