• Relative molecular weight of NiBr2: 218.5014
• Molar mass of NiBr2: 218.5014 g/mol (0.2185 kg/mol)

Calculation of the relative molecular and molar mass of NiBr2

• Mr[NiBr2] = Ar[Ni] + Ar[Br] * 2 = 58.6934 + 79.904 * 2 = 218.5014
• Molar mass (kg/mol) = Mr[NiBr2] : 1000 = 218.5014 : 1000 = 0.2185 kg/mol

NiBr2: percent composition by element
