Give me all right solutions with clear calculations 

1.0 gram of air is in a piston-cylinder assembly of volume 500 cm and is at 200 kPa. The air
is compressed slowly by 22.4 Joules of work. 4.1 Joules of heat are given off by the cylinder
to the surroundings.
Calculate:
a) the number of moles of air
b) the initial temperature of the air ,
c) the final temperature of the air if the air has a c, = 0.733
J/(g*K)
