Molar and molecular weight of BiCl3

• Relative molecular weight of BiCl3: 315.3394
• Molar mass of BiCl3: 315.3394 g/mol (0.31534 kg/mol)

Calculation of the relative molecular and molar mass of BiCl3

• Mr[BiCl3] = Ar[Bi] + Ar[Cl] * 3 = 208.9804 + 35.453 * 3 = 315.3394
• Molar mass (kg/mol) = Mr[BiCl3] : 1000 = 315.3394 : 1000 = 0.31534 kg/mol

BiCl3: percent composition by element
