Calculate the energy in calories lost when 30.0 ethanol, , cools from 56.5 degree Celsius to -42.0 degree Celsius.

  • Chemistry -

    30 what? grams.?
    The freezing point for ethanol is -114 C; therefore, it does not go through a phase change from 56.5 to -42.0
    q = mass x specific heat x (Tfinal-Tinitial)
