Homework Help: heat of vaporization

Posted by Kyle on Saturday, January 16, 2010 at 2:35pm.

Suppose that 1.00 g of rubbing alcohol (C3H8O) evaporates from a 54.0 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.

45.4 kJ/mole for the heat of vaporization of rubbing alcohol
The specific heat of Al is 0.903 J/g*C
