To determine the heat required to vaporize a given substance at its boiling point, you just have to multiply the mass of the sample to the heat of vaporization of the substance. Therefore, the heat is required to vaporize 1.5 kg of liquid water would be 3.4 x 10^6 J. Hope this answers the question.
