Molar and molecular weight of C7H4BrNO

• Relative molecular weight of C7H4BrNO: 198.01676
• Molar mass of C7H4BrNO: 198.01676 g/mol (0.19802 kg/mol)

Calculation of the relative molecular and molar mass of C7H4BrNO

• Mr[C7H4BrNO] = Ar[C] * 7 + Ar[H] * 4 + Ar[Br] + Ar[N] + Ar[O] = 12.0107 * 7 + 1.00794 * 4 + 79.904 + 14.0067 + 15.9994 = 198.01676
• Molar mass (kg/mol) = Mr[C7H4BrNO] : 1000 = 198.01676 : 1000 = 0.19802 kg/mol
