500 g of ice at -20°C is dropped into a copper vessel at 300°C. The vessel then holds 450 g of ice mixed with water. $c_{Cu}=0.1\mathrm{cal}/\left({\mathrm{g}}^{\circ }\mathrm{C}\right),c_{\text{ice }}=0.5\mathrm{cal}/\left({\mathrm{g}}^{\circ }\mathrm{C}\right),L_f=80\mathrm{cal}/\mathrm{g}$. Find the mass of the vessel in g.
