Molar and molecular weight of CuI

• Relative molecular weight of CuI: 190.45047
• Molar mass of CuI: 190.45047 g/mol (0.19045 kg/mol)

Calculation of the relative molecular and molar mass of CuI

• Mr[CuI] = Ar[Cu] + Ar[I] = 63.546 + 126.90447 = 190.45047
• Molar mass (kg/mol) = Mr[CuI] : 1000 = 190.45047 : 1000 = 0.19045 kg/mol

CuI: percent composition by element

• Copper (Cu) = 63.546 : 190.45047 * 100 = 33.366 %
• Iodine (I) = 126.90447 : 190.45047 * 100 = 66.634 %
