Molar and molecular weight of (NH4)2S

• Molecular formula: (NH4)2S or H8N2S
• Relative molecular weight of (NH4)2S: 68.14192
• Molar mass of (NH4)2S: 68.14192 g/mol (0.06814 kg/mol)

Calculation of the relative molecular and molar mass of (NH4)2S

• Mr[(NH4)2S] = Ar[H] * 8 + Ar[N] * 2 + Ar[S] = 1.00794 * 8 + 14.0067 * 2 + 32.065 = 68.14192
• Molar mass (kg/mol) = Mr[(NH4)2S] : 1000 = 68.14192 : 1000 = 0.06814 kg/mol

(NH4)2S: percent composition by element

• Hydrogen (H) = 8.06352 : 68.14192 * 100 = 11.833 %
• Nitrogen (N) = 28.0134 : 68.14192 * 100 = 41.11 %
• Sulfur (S) = 32.065 : 68.14192 * 100 = 47.056 %
