Molar and molecular weight of O2Re

• Molecular formula: O2Re or ReO2
• Relative molecular weight of O2Re: 218.2058
• Molar mass of O2Re: 218.2058 g/mol (0.21821 kg/mol)

Calculation of the relative molecular and molar mass of O2Re

• Mr[O2Re] = Ar[O] * 2 + Ar[Re] = 15.9994 * 2 + 186.207 = 218.2058
• Molar mass (kg/mol) = Mr[O2Re] : 1000 = 218.2058 : 1000 = 0.21821 kg/mol

O2Re: percent composition by element

• Oxygen (O) = 31.9988 : 218.2058 * 100 = 14.665 %
• Rhenium (Re) = 186.207 : 218.2058 * 100 = 85.335 %
