The latent heat of vaporization of water is 540 calories/gram. How many calories are required to completely vaporize 500 grams of water?

    1 g = 540 calories
    500 g = ? calories

    Since the mass is 500 times 1 g, so the number of calories
    = 500*540 calories

    Oh, so you just set it up like a proportion?
    And thank you. (:
