**Effusion Time Problem**

A sample of Br₂(g) takes 28.0 minutes to effuse through a membrane. How long would it take the same number of moles of Ar(g) to effuse through the same membrane?

**Time Calculation:**

- Input Box: [                    ] min

This problem can be approached using Graham's Law of Effusion, which states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. You will compare the rates of Br₂ and Ar to calculate the required time for Ar to effuse.
