A piece of plastic at 161 degree C was put in a beaker with 105.9 g ethanol at 20.5 degree C . The temperature of the water rose to 39 degree C. Given that the specific heat of ethanol is 2.46 J/g degree C, what is the heat capacity of the piece of plastic in J/degree C? Use proper sig figs. Gracias!
