A student mixes 85.1 g of water at 69.6°C with 58.1 g of water at 22.0°C in an insulated flask. What is the final temperature of the combined water?

• Chemistry -

heat lost by warm water + heat gained by cool water = 0

[mass warm H2O x specific heat H2O x (Tfinal-Tinnitial)] + [mass cool water x specific heat H2O x (Tfinal-Tinitial)] = 0. Solve for Tfinal
