QUESTION 9 Two identical containers are filled with two different gases

QUESTION 9 Two identical containers are filled with two different gases with equal moles; one of them is filled with N, and the other one is filled with an unknown gas, and kept under vacuum conditions. When both containers are opened with identical holes, the pressure of the container which is filled with N, dropped to 0.3 of its initial pressure within 50 seconds, whereas the pressure of the container which is filled with unknown gas dropped to 0.7 of its initial pressure within 45 seconds. Find molecular weight of the unknown gas. Assume 7N: 14.007 g mol-1
