Answer:

Mass of  CuCl₂ = 23.125 g

Explanation:

Given data:

Number of moles of CuCl₂ = 0.172 mol

Mass of CuCl₂ = ?

Solution:

First of all we will calculate the molar mass of CuCl₂.

Molar mass of CuCl₂ = 63.546 + 2(35.5)

Molar mass of CuCl₂ = 134.45 g/mol

Formula:

Number of moles = mass / molar mass

Mass =  Number of moles × molar mass

Mass =  0.172 mol × 134.45 g/mol

Mass = 23.125 g
