Molar and molecular weight of HKS

• Molecular formula: HKS or KHS
• Relative molecular weight of HKS: 72.17124
• Molar mass of HKS: 72.17124 g/mol (0.07217 kg/mol)

Calculation of the relative molecular and molar mass of HKS

• Mr[HKS] = Ar[H] + Ar[K] + Ar[S] = 1.00794 + 39.0983 + 32.065 = 72.17124
• Molar mass (kg/mol) = Mr[HKS] : 1000 = 72.17124 : 1000 = 0.07217 kg/mol

HKS: percent composition by element

• Hydrogen (H) = 1.00794 : 72.17124 * 100 = 1.397 %
• Potassium (K) = 39.0983 : 72.17124 * 100 = 54.174 %
• Sulfur (S) = 32.065 : 72.17124 * 100 = 44.429 %
