Molar and molecular weight of HKO4S

• Molecular formula: HKO4S or KHSO4
• Relative molecular weight of HKO4S: 136.16884
• Molar mass of HKO4S: 136.16884 g/mol (0.13617 kg/mol)

Calculation of the relative molecular and molar mass of HKO4S

• Mr[HKO4S] = Ar[H] + Ar[K] + Ar[O] * 4 + Ar[S] = 1.00794 + 39.0983 + 15.9994 * 4 + 32.065 = 136.16884
• Molar mass (kg/mol) = Mr[HKO4S] : 1000 = 136.16884 : 1000 = 0.13617 kg/mol

HKO4S: percent composition by element

• Hydrogen (H) = 1.00794 : 136.16884 * 100 = 0.74 %
• Potassium (K) = 39.0983 : 136.16884 * 100 = 28.713 %
• Oxygen (O) = 63.9976 : 136.16884 * 100 = 46.999 %
• Sulfur (S) = 32.065 : 136.16884 * 100 = 23.548 %
