Suppose that 1.00 g of rubbing alcohol (C3H8O) evaporates from a 57.0g aluminum block If the aluminum block is initially at 25 C, what is the final temperature of the block after the evaporation of the alcohol? Assume that the heat required for the vaporization of the alcohol comes only from the aluminum block and that the alcohol vaporizes at 25 C.

What values are you using for heat vaporization of rubbing alcohol and heat capacity of Al. My numbers are from an old text and probably won't agree with yours.
