posted by carl . Could you help me with this homework please..105.0 g of water is in a Styrofoam calorimeter of negligible heat capacity. The initial T of the water is 17.1oC. After 288.2 g of an unknown compound at 77.0oC is added, the equilibrium T is 25.1oC. What is the specific heat of the unknown compound in J/(goC)?heat lost by unknown compound + heat gained by H2O = 0 [mass unknown x specific heat unk x (Tfinal-Tinitial)] +[mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0Substitute and solve for specific heat unknown.
