Suppose that 0.88 g of water vapor condenses on a 75.0 g block of iron that is initially at 22 Degree C. If the heat released during condensation goes only to warming the iron block, what is the final temperature (in Degree C) of the iron block? (Assume a constant heat of vaporization of 44.0 kJ/mol for water; C_Fe = 0.449 J/g degree C) Gold crystallizes in a face-centered cubic structure. What is the edge length of the unit cell if the atomic radius of gold is 144 pm?
