Please help how to solve this question
An unknown metal weighting 13.11 g at a temperature of 81.0 degrees Celius is place in a calorimeter containing 25.0 mL of water at a temperature of 25.0 degrees Celsius. The final equilibrium temperature is 30.0 degrees Celius. What s the specific heat of the metal? The specific heat of water is 4.184 J/g-C. Assume the density of water is 1.00g/mL and that there is no heat lost or gained by the calorimeter.
