A 100.0 g sample of water at 27.0°C is poured into a 77.4 g sample of water at 89.0°C. What will be the final temperature of the water?

  • Chemistry -

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

  • Chemistry -

    M= 100.0-g
    C=2.06J/gC
    Ti=116
    Tf=75.0
