A 37.0 g sample of glass, which has a specific heat capacity of 0.670 J·g ·℃、is dropped into an insulated container containing 250.0 g of water at 15.0 °C and a constant pressure of 1 atm. The initial temperature of the glass is 89.6 °C. Assuming no heat is absorbed from or by the container, or the surroundings, calculate the equilibrium temperature of the water. Be sure your answer has the correct number of significant digits oC x 10
