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.

Question

somebody asked this question earlier today but I'd be happy to recap my solution

hourly rate (0.105 mol/hr) * 12 hours will give you the amount of moles leaked

total moles (2.75) - the amount of moles leaked will give you the remaining amount of moles

then use avogadro's principle to solve for V_final where

V_final/n_final = V_initial/n_initial
