Answer to Question #57790 in Physical Chemistry for Hannah

Question #57790
A .3M solution of HCl with a volume of 450 mL is poured into a chemically resistant balloon which contains excess zinc metal and which is otherwise empty. The balloon is immediately sealed. The HCl in solution completely reacts with the zinc metal forming zinc ions and H2 gas that expands the balloon. Assuming the balloon expands against constant pressure of 1.10 atm at the contant temperature of 20 celcius calculate the expansion work done on the gas. Assume the gas is ideal and that the volume of the liquid does not change.
