Task id12834

A closed vessel is divided into two equal parts by a solid, stationary, semi-permeable partition. A mixture of argon and hydrogen was introduced into the first half of the vessel at a pressure of P = 1.5 atm, and a vacuum was introduced into the second half. Only hydrogen can diffuse through the partition. After the end of the diffusion process, the pressure in the first half turned out to be P = 1 atm. The temperature was kept constant during the process. Determine the ratio of the masses of argon and hydrogen in the mixture that was initially introduced into the first half of the vessel. The atomic weight of argon is Ma = 40, the molecular weight of hydrogen is Mw = 2.
