Answer to Question #281220 in General Chemistry for majo

Question

Calculate the ratio of the rate of effusion of methane gas ,CH4(g)at constant temperature and pressure The molar masses or CH4(g) and He (g) are 16.0 g/mol and 4.0 g/mol , respectively

Answer 1

Ratio of rate of Diffusion of methane and Helium gas = under root of 4 / 16

= 1/2 .

So, rate of Diffusion of He gas is double of rate of Diffusion of methane gas .
