Molar and molecular weight of OSr

• Molecular formula: OSr or SrO
• Relative molecular weight of OSr: 103.6194
• Molar mass of OSr: 103.6194 g/mol (0.10362 kg/mol)

Calculation of the relative molecular and molar mass of OSr

• Mr[OSr] = Ar[O] + Ar[Sr] = 15.9994 + 87.62 = 103.6194
• Molar mass (kg/mol) = Mr[OSr] : 1000 = 103.6194 : 1000 = 0.10362 kg/mol

OSr: percent composition by element

• Oxygen (O) = 15.9994 : 103.6194 * 100 = 15.441 %
• Strontium (Sr) = 87.62 : 103.6194 * 100 = 84.559 %
