Calculate the mass of Glauber's salt needed to lower the temp of air in a room by 6.3 C. The mass of air in the room is 555.4 kg, the specific heat is 1.2J/g-c
The heat needed to change T by 6.3 C is
q = 555400g x 1.2 J/g*c x 6.3
You will need to know the heat information for Na2SO4.10H2O to do the remaining part of the problem.
