Question
When 155 mL of water at 26 degrees Celsius is mixed with 75 mL of water at 95 degrees Celsius, what is the final temperature of the mixture? (d Water = 1.00 g/mL)
Im really stuck on this problem and chemistry isnt exactly my strong point,
thanks in advance!

heat gained by cold water + heat lost by warm water = 0
[mass cold H2O x specific heat H2O x (Tfinal-Tinitial)] + [mass warm H2O x specific heat H2O x (Tfinal-Tinitial)] \ 0
Substitute and solve for the only unknown, which is Tf.
