Molar and molecular weight of CuFeS2

• Relative molecular weight of CuFeS2: 183.521
• Molar mass of CuFeS2: 183.521 g/mol (0.18352 kg/mol)

Calculation of the relative molecular and molar mass of CuFeS2

• Mr[CuFeS2] = Ar[Cu] + Ar[Fe] + Ar[S] * 2 = 63.546 + 55.845 + 32.065 * 2 = 183.521
• Molar mass (kg/mol) = Mr[CuFeS2] : 1000 = 183.521 : 1000 = 0.18352 kg/mol

CuFeS2: percent composition by element

• Copper (Cu) = 63.546 : 183.521 * 100 = 34.626 %
• Iron (Fe) = 55.845 : 183.521 * 100 = 30.43 %
• Sulfur (S) = 64.13 : 183.521 * 100 = 34.944 %
