How much heat must be expended to convert 100 g of water into steam at normal atmospheric pressure?

How much heat must be expended to convert 100 g of water into steam at normal atmospheric pressure? The specific heat of vaporization of water is 2.3 * 10 ^ 6 J / kg.

Q = Lm = 2,300,000 * 0.1 = 230,000 J
