A generic reaction takes place inside of an 5 L balloon at 1 atm and 293 K (i.e the pressure and temperature is constant). What is the final volume of the balloon if the reaction taking place is:

2 A + 2 B --- 3 C

You can assume all the products and reactants are in the gas phase, the reaction goes to completion, and the partial pressure of A and B are initially equivalent. Give your answer in L to the first decimal place.
