A biology experiment requires the preparation of a water bath at 37.0°C (body temperature). The temperature of the cold tap water is 22.0°C, and the temperature of the hot tap water is 55.0°C. If a student starts with 70.0 g of cold water, what mass of hot water must be added to reach 37.0°C?

  • chemistry - ,

    mass cold water x specific heat x (Tfinal-Tinitial) + mass hot water x specific heat x (Tfinal-Tinitial) = 0

    Solve for mass hot water.
