Molar and molecular weight of ReCl5

• Molecular formula: ReCl5 or Cl5Re
• Relative molecular weight of ReCl5: 363.472
• Molar mass of ReCl5: 363.472 g/mol (0.36347 kg/mol)

Calculation of the relative molecular and molar mass of ReCl5

• Mr[ReCl5] = Ar[Cl] * 5 + Ar[Re] = 35.453 * 5 + 186.207 = 363.472
• Molar mass (kg/mol) = Mr[ReCl5] : 1000 = 363.472 : 1000 = 0.36347 kg/mol

ReCl5: percent composition by element

• Chlorine (Cl) = 177.265 : 363.472 * 100 = 48.77 %
• Rhenium (Re) = 186.207 : 363.472 * 100 = 51.23 %
