1. KMnO_(4)=underline ( )g % K=underline ( ) % Mn=underline ( ) % O=underline ( )

To determine the percentage composition of each element in potassium permanganate (KMnO₄), we need to calculate the molar mass of KMnO₄ and then find the mass percentage of each element.1. **Calculate the molar mass of KMnO₄:** - Potassium (K): 39.10 g/mol - Manganese (Mn): 54.94 g/mol - Oxygen (O): 16.00 g/mol The molar mass of KMnO₄ is: 2. **Calculate the percentage composition of each element:** - **Potassium (K):** - **Manganese (Mn):** - **Oxygen (O):** So, the percentage composition of each element in KMnO₄ is:- Potassium (K): 24.74%- Manganese (Mn): 34.76%- Oxygen (O): 40.50%
