0.859g of hydrated copper (II) chloride consisters of 0.320g copper, 0.358g chlorine, 0.0200g hydrogen and 0.161g of oxygen. They hydrogen and the oxygen are present as water of crystallisation. What is the formula of the hydrated salt?
I worked out that there was 0.678g of CuCl2 and 0.181g of water
Did the whole shabang and worked out the moles etc etc and got the formula as:
CuCl2.2H2O
Can someone pleaseeeeeee check i've done this correct because im not ENTIRELY confident
