4] Energy needed to remove = latent heat of evaporation + heat for decreasing temperature + latent heat of vaporization
= 0.535*[879 +2.43*(78--114)+109]
= 778 kJ (not kg)
Your unit is wrong
5] work done = heat - change in internal energy
= 196 - [0-76.1 - -178]
= 94.1 J

The figure displays a closed cycle for a gas (the figure is not
drawn to scale). The change in the internal energy of the gas as it
moves from a to c along the path abc is
-189 J. As it moves from c to d, 178 J must be
transferred to it as heat. An additional transfer of 83.9 J to it
as heat is needed as it moves from d to a.
