Molar and molecular weight of C3H6

• Relative molecular weight of C3H6: 42.07974
• Molar mass of C3H6: 42.07974 g/mol (0.04208 kg/mol)

Calculation of the relative molecular and molar mass of C3H6

• Mr[C3H6] = Ar[C] * 3 + Ar[H] * 6 = 12.0107 * 3 + 1.00794 * 6 = 42.07974
• Molar mass (kg/mol) = Mr[C3H6] : 1000 = 42.07974 : 1000 = 0.04208 kg/mol

C3H6: percent composition by element

• Carbon (C) = 36.0321 : 42.07974 * 100 = 85.628 %
• Hydrogen (H) = 6.04764 : 42.07974 * 100 = 14.372 %
