2Al + 3CuCl2 ➡ 2AlCl3 + 3Cu.
Moles of Al = 1.2/27 = 0.045 moles
2 moles of Al reacts with 3 moles of CuCl2.
Therefore, 1 mole of CuCl2 reacts with =2/3 x moles of Al
= 2/3 x 0.045
= 0.03 moles.
There is no need to do anything about the temperature, because sublimation does not involve any temperature change.
First, determine how many moles of CO2 there are. The mol. wt. of CO2 is 12 +2 x 16 = 44 g/mol.
So, 25.0 equals 25/44 = 0.568 moles
So the heat required is 0.568 mol x 32.3 KJ/mol = 18.3
