For 10 minutes each, at 27 degree celsius,from two identical holes nitrogen and an unknown gas are leaked into a common vessel of 3L capacity.The resulting pressure is 4.18 bar and its mixture contains 0.4 moles of nitrogen.What is the molar mass of the unknown gas?

I am attaching an image of the solution. I calculated the no of moles of each gas in the container and then compared to find the respective rate of diffusion of gases. Thereafter I applied the diffusion-molar mass relation. Hope it helps.
