okay, the heat energy from the alloy is used to increase the temperature of water from 25 to 37C
so you can figure out the heat energy gained by water.
$$Q=m \times c  \times \Delta T$$

then use the value of heat energy and all the given value for the alloy  to find the heat capacity of the alloy in the same equation.
