(0.994 g CuCl) / (98.999 g CuCl/mol) x (1 mol Cu / 1 mol CuCl) x (63.5463 g Cu/mol) = 0.638 g Cu
(0.994 g total) - (0.638 g Cu) = 0.356 g Cl

Copper atomic mass: 63.546 u.
Chlorine atomic mass: 35.453 u.
So the ratio of the masses is 63.546 : 35.453. The sum of the atomic masses is 98.999.
Take the mass you have (0.995 g) and divide by 98.999. Then multiply by 63.546 to get the mass of Cu, or by 35.453 to get the mass of Cl.
