Part B: How much faster?

Hello!

Use the equation:

CH4 rate of effusion / He rate of effusion = sqrt(He molar mass / CH4 molar mass)

He molar mass = 4 g/mol (approximate)

CH4 molar mass = 16 g/mol (approximate)

CH4 rate of effusion = He rate of effusion * sqrt(4/16)

CH4 rate of effusion = (1/2) He rate of effusion

This shows that CH4 rate of effusion is half of He rate of effusion.

He effuses twice as fast as CH4.

Hope this helps and let me know if you have any questions :)
