Molar and molecular weight of KPO3

• Molecular formula: KPO3 or KO3P
• Relative molecular weight of KPO3: 118.070262
• Molar mass of KPO3: 118.070262 g/mol (0.11807 kg/mol)

Calculation of the relative molecular and molar mass of KPO3

• Mr[KPO3] = Ar[K] + Ar[O] * 3 + Ar[P] = 39.0983 + 15.9994 * 3 + 30.973762 = 118.070262
• Molar mass (kg/mol) = Mr[KPO3] : 1000 = 118.070262 : 1000 = 0.11807 kg/mol

KPO3: percent composition by element

• Potassium (K) = 39.0983 : 118.070262 * 100 = 33.114 %
• Oxygen (O) = 47.9982 : 118.070262 * 100 = 40.652 %
• Phosphorus (P) = 30.973762 : 118.070262 * 100 = 26.233 %
