Explanation:

mole=mass/Molar mass

mass= mole×molar mass

m= 1.5 × (39+55+64)

m= 1.5 × 158

m= 237g

There are 237.06 grams in 1.50 moles of KMnO4.

HOW TO CALCULATE MASS:

  • The mass of a substance can be calculated by multiplying the number of moles in the substance by its molar mass. That is;

  • mass of KMnO4 = no. of moles × molar mass of KMnO4

  • Molar mass of KMnO4 = 39 + 55 + 16(4)

= 158g/mol

  • mass of KMnO4 = 158g/mol × 1.5mol

  • Mass of KMnO4 = 237g

  • Therefore, there are 237.06 grams in 1.50 moles of KMnO4.
