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!

1 answer

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.
