WebJul 21, 2024 · The molecule may have a molecular formula of CH 2 O, C 2 H 4 O 2, C 3 H 6 O 3, or the like. As a result, the compound may have a gram molecular mass of 30 g/mol, 60 g/mol, 90 g/mol, or another multiple of 30 g/mol. You can't calculate a molecular formula based on percent composition alone.
WebUse Molar Mass Formula. Solution: The molar mass of molecules of those elements is equal to the molar mass of the atoms multiplied by the number of atoms in each molecule. Therefore, Molar Mass of (H2) = 2 × 1.007 97 (7) × 1.000000 g/mol = 2.01588 (14) g/mol Molar Mass (S8) = 8 × 32.065 (5) × 1.000000 g/mol = 256.52 (4) g/mol flight risk at workWebBy 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.
