Molar and molecular weight of MoS2

• Relative molecular weight of MoS2: 160.07
• Molar mass of MoS2: 160.07 g/mol (0.16007 kg/mol)

Calculation of the relative molecular and molar mass of MoS2

• Mr[MoS2] = Ar[Mo] + Ar[S] * 2 = 95.94 + 32.065 * 2 = 160.07
• Molar mass (kg/mol) = Mr[MoS2] : 1000 = 160.07 : 1000 = 0.16007 kg/mol

MoS2: percent composition by element

• Molybdenum (Mo) = 95.94 : 160.07 * 100 = 59.936 %
• Sulfur (S) = 64.13 : 160.07 * 100 = 40.064 %
