Heat absorbed by H2O will be equal to Heat transferred by metal
Heat transferred by metal = 112.72 J
(m* Cp* delT)water = (m* Cmetal * delT)metal
26.674 g * 4 J/g.C * 1.01 C = 3.326 g * Cmetal * 21.02 C
Cmetal = 1.54 J/g.C
Iron
heat transfered by metal = 81.74 J
(m* Cp* delT)water = (m* Cmetal * delT)metal
19.733 g * 4 J/g.C * 0.99 C = 10.267 g * Cmetal * 21.03 C
Cmetal = 0.362 J/g.C

In an experiment, 26.0 g of metal was heated to 98.0°C and then quickly transferred to 150.0 g of water in a calorimeter. The initial temperature of the water was 26.0°C, and the final temperature after the addition of the metal was 32.5°C. Assume the calorimeter behaves ideally and does not absorb or release heat. What is the value of the specific heat capacity (in J/g•°C) of the metal?
