A puncture in the tubing of a refrigerator can cause severe frosbite as chloroethane C2H5Cl, vaporizes. Use this thermochemical equation to calculate the heat absprbed when 23.6g of chloroethane vaporizes at its boiling point (9.66kj)
C2H5Cl + 26.4kj arrow C2H5Cl.

pls i need help. what si the formula to use? and how do i solve it pls help

Your equation makes no sense. You should have (l) by the liquid and (g) by the gas phase.
Also, what is the difference between the 9.66 kJ ad the 26.4 kJ?
