rubbing alcohol

Suppose that 1.04 g of rubbing alcohol (C3H8O) evaporates from a 53.0 −g 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. Rubbing alcohol (C3H8O) has a heat of vaporization of 45.4 kJ/mol.

 

Express your answer using two significant figures.
