A 25.0 L balloon is filled with 2.75 mol of helium. If the helium leaks out at the rate of 0.105 mol/hr, what is the volume of the balloon after 12.0 hr? Assume the pressure and temperature don’t change.

"0.105 mol/hr, what is the volume of the balloon after 12.0 hr"

hourly rate * hours will give the amount of moles leaked 
then subtract 25.0 - amount of moles leaked to get the final amount of moles

then use avogadro's principle

V_final/n_final = V_initial/n_initial
to solve for V_final
