A mass of 336.8 g having unknown composition is heated in an oven to a temperature of around 312.14 °C. The mass is then dropped to a strong insulated calorimeter having 949.4 g of water. The initial temperature of water is around 11.36 °C. The final equilibrium temperature of the system is around 15.78 °C. Suppose that the mass and water are in an isolated system and the water doesn’t vaporize. No heat is transferred to the water throughout the experiment. The specific heat of the water is around 4190 J/kg-K. Determine the specific heat of the unknown mass?
