Answer: 0.21 mole
Explanation:
Atomic mass of Potassium, K = 39.1g/mol
Atomic mass of Manganese, Mn = 54.9g/mol
Atomic mass of Oxygen, I = 16g/mol
First find the molar mass of KMnO4, that is
KMnO4 = 39.1+54.9+(16)4
Molar mass of KMnO4 = 158g/mol
Hence,
1 mole of KMnO4 = 158g
Let x mole of KMnO4 = 33g
x = 33/158 mole
x = 0.21 mole
