4.5g

Explanation:

Given parameters:

  Mass of copper(i)chloride  = 6.93g

Unknown:

Mass of copper  = ?

Solution:

Formula of the compound  = CuCl

        atomic mass of Cu = 63.6g/mol,  atomic mass of Cl  = 35.5g/mol

  Molecular mass = 63.6 + 35.5  = 99.1g/mol

 So,

   The mass of copper = x 6.93 = 4.5g
