Molar and molecular weight of KBrO4

• Molecular formula: KBrO4 or BrKO4
• Relative molecular weight of KBrO4: 182.9999
• Molar mass of KBrO4: 182.9999 g/mol (0.183 kg/mol)

Calculation of the relative molecular and molar mass of KBrO4

• Mr[KBrO4] = Ar[Br] + Ar[K] + Ar[O] * 4 = 79.904 + 39.0983 + 15.9994 * 4 = 182.9999
• Molar mass (kg/mol) = Mr[KBrO4] : 1000 = 182.9999 : 1000 = 0.183 kg/mol

KBrO4: percent composition by element

• Bromine (Br) = 79.904 : 182.9999 * 100 = 43.663 %
• Potassium (K) = 39.0983 : 182.9999 * 100 = 21.365 %
• Oxygen (O) = 63.9976 : 182.9999 * 100 = 34.971 %
