Molar and molecular weight of CH4

• Relative molecular weight of CH4: 16.04246
• Molar mass of CH4: 16.04246 g/mol (0.01604 kg/mol)

Calculation of the relative molecular and molar mass of CH4

• Mr[CH4] = Ar[C] + Ar[H] * 4 = 12.0107 + 1.00794 * 4 = 16.04246
• Molar mass (kg/mol) = Mr[CH4] : 1000 = 16.04246 : 1000 = 0.01604 kg/mol

CH4: percent composition by element

• Carbon (C) = 12.0107 : 16.04246 * 100 = 74.868 %
• Hydrogen (H) = 4.03176 : 16.04246 * 100 = 25.132 %
