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

• IPC -

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. (:
