Question

In an effusion experiment, it was determined that nitrogen gas, n2, effused at a rate 1.812 times faster than an unknown gas. What is the molar mass of the unknown gas?

Answer 1

Answer:

Approximately 92 grams (= 91.93 grams)

Explanation:

Molar mass of gas = (1.812)^2 * Molar mass of N2

By Graham's Law Of Diffusion (can be applied for effusion also).
