How much heat is required to vaporize 3.50L of at its normal boiling point?

The following data are given for Carbon Tetrachloride. Normal melting point, -23 Degrees Celsius, normal boiling point, 77 Degrees Celsius; density of liquid, 1.59g/mL; Delta H (FUSION): 3.28 kJ mol^-1; vapor pressure at 25 Degrees Celsius, 110 Torr.

**I don't know how to find the heat of vaporization, though when the boiling point is 77 degrees celsius, I found that the heat of vaporization if 192J/g, allowing the FINAL answer to equal to 1068.48kJ, because I was told to be wrong, can someone please correct me?

Thank you.
