Explain what was the delta t for the metal

Reference no: EM13301661

A metal sample weighing 124.10g and at a temperature of 99.3C was placed in 42.87g of water in a calorimeter at 23.9C. At equilibrium the temperature of the water and metal was 41.6C. a) what was the delta t for the water? b) what was the delta t for the metal? c) how much heat flowed into the water? d) taking the specific heat of water to be 4.18J/gC, calculate the specific heat of the metal e) what is the approximate molar mass of the metal using the equation MM=25/S.H.(J/gC)
