A calorimeter is constructed of 600 grams of glass (Cs = 0.75 J/gC) and it contains 300 grams toluene (Cs = 2.24 J/gC). The initial temp of the calorimeter (both glass and toluene together) is 25C. If 60 J of heat is added to calorimeter calculate the final temp of calorimeter (both glass and toluene together) assuming no heat is lost to surroundings.
