Respuesta :
0.158 moles
Number of moles is defined as the ratio between given mass and molar mass.
Given:
Mass= 25.0 grams
To find:
Molar mass=?
Molar mass of KMnO₄ = 158 g/mol
[tex]\text{Number of moles}= \frac{\text{Given mass}}{\text{Molar mass}} \\\\\text{Number of moles}=\frac{25}{158} \\\\\text{Number of moles}=0.158 \text{ moles}[/tex]
Thus, the number of moles of potassium permanganate, KMnO₄ is 0.158 moles.
