How would I calculate this?

30.0 mL of pure water at 280. K is mixed with 50.0 mL of pure water at 307 K. What is the final temperature of the mixture?

  • Chemistry -

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

    [mass warm water x specific heat water x (Tfinal-Tinitial)] + [mass cool water x specific heat H2O x (Tfinal-Tinitial)] = 0
    Substitute and solve for Tf.
