Answer:
The answer to your question is 1.46 moles of KMnO₄
Explanation:
Data
number of moles = ?
mass = 230.8 g
molecular mass of KMnO₄ = 39 + 55 + (16 x 4) = 158 g
Process
1.- Use proportions and cross multiplication to answer this problem.
158 g of KMnO₄ ---------------- 1 mol
230.8 g of KMnO₄ ----------- x
x = (230.8 x 1) / 158
2.- Simplifying
x = 230.8 / 158
3.- Result
x = 1.46 moles
