Question 2

125 g of dry ice (solid CO2) is dropped into a beaker containing 500 g of 66C water. The dry ice converts directly to gas, leaving the solution. When the dry ice is gone, the final temperature of the water is 29C. What is the heat of vaporization of solid CO2? (cwater = 1.00 cal/gC)
a. 37 cal/g
c. 111 cal/g
b. 74 cal/g
d. 148 cal/g
