You multiply the mass of the silver by its heat of fusion.

The heat of fusion (#ΔH_("fus")#) is the amount of heat required to melt a unit mass of a solid.

#q = mΔH_("fus")#, where #q# is the amount of heat and #m# is the mass of the sample.

The heat of fusion of silver is 111 kJ/kg, so

#q = mΔH_("fus")# = 15 kg × #(111" kJ")/(1" kg")# = 1700 kJ
