Donovan Skinner · Answer 1

Number of moles = 0.92 mol

Explanation:

Given dа ta:

Mass of CaSO₄ = 125 g

Number of moles of CaSO₄ = ?

Solution:

Formula:

Number of moles = mass / molar mass

Molar mass of CaSO₄:

Molar mass of CaSO₄ = 40 + 32 + 16*4

Molar mass of CaSO₄ = 40 + 32 + 64

Molar mass of CaSO₄ = 136 g/mol

Number of moles:

Number of moles = mass / molar mass

Number of moles = 125 g / 136 g/mol

Number of moles = 0.92 mol
