Question

A 10 g sample of water at 24 Celsius is mixed with 30.0 g of water at 48 Celsius. Calculate the final temperature of the mixture assuming no heat loss to the surroundings. The specific heat of water is 4.18 j/g•C
heat lost by water + heat gained by cool water = 0

[mass warm H2O x specific heat H2O x (Tfinal - Tinitial)] + [mass cool H2O x specific heat H2O x (Tfinal-Tinitial)] = 0. Tfinal is the only unknown. Substitute and solve for it.
28.0
