There is a certain mass of pure metal D in 79.0 g of water and both of them are at 27.5 C. 82.0 g of water at at 91.7 C is then added. After stirring, thermal equilibrium is reached and the final uniform temperature is 59.4 C. Assuming no loss of energy to the surroundings, calculate the mass of metal D. Give your answer with 3 significant figures. Specific heat capacity of water: 4.184 J/gC Specific heat capacity of metal D: 0.730 J/gC (Hint: Consider this as an isolated system that has three different components inside.)
