Propane (C3H8) boils at ‐42.0 °C with a heat of vaporization of 19.0 kJ/mol. Calculate the heat involved in bringing 50.0 mL of liquid propane at ‐50.0° C  to 20.0 °C.       Data:  liquid propane density = 2.01 g/cm3, specific heat capacity of liquid propane = 1.32 J g‐1 °C‐1 , specific heat capacity of gaseous propane = 1.64 J g‐1 °C‐1 . Assume heat capacity does not vary with temperature.
