Calculate the amount of energy (in kJ) necessary to convert 537g

Calculate the amount of energy (in kJ) necessary to convert 537g of liquid water from 0degree celsius to water vapor at 162degree celsius. The molar heat of vaporization of water is 40.79 kJ/mol. The specific heat for water is 4.184J/g degree celsius and for steam is 1.99 J/g * degree celsius. (Assume that the specific heat values do not change over the range of temperatures in the problem.)
