$$COP = 8.53$$ $$m = 1103 \ kg$$
We know that COP is given by: $$COP = \frac{T_c}{Tc+T_h}$$ We plug in the values in Kelvin to have: $$COP = 8.53$$ We know $$COP = \frac{mL}{W}$$ We know that the latent heat of fusion for water is .334 MJ/kg. We plug in the given values to obtain: $$m = 1100 \ kg$$
