a student mixes 88.6g of water at 74.3 degree Celsius with 57.9g of water at 24.8 degree Celsius in an insulated flask.What is the final temperature of the combined water.

  • 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 water x T(final-Tinitial)] = 0
    Solve for Tfinal.

  • chemistry -

    54.7 degrees C
