Question

If 1dm^3 of gas x diffuses through a porous plug in 60s

Answer 1

Answer:

Explanation:

2.278 x 10¯ 4 mol of an unidentified gaseous substance effuses through a tiny hole in 95.70 s. Under identical conditions, 1.738 x 10¯ 4 mol of argon gas takes 81.60 s to effuse. What is the molar mass of the unidentified substance? Solution: 1) The first thing we need to do is compute the rate of effusion for each gas

this is just an example for you to understand
