Question

the rate of effusion of h2 as compared to an unknown gas is 4.673 times faster. calculate the molar mass of the unknown gas. the rate of effusion of h2 as compared to an unknown gas is 9 times faster. calculate the molar mass of the unknown gas. he diffuses 4 times faster than an unknown gas. what is the molar mass of the unknown gas? a carbon dioxide molecule travels at 45.0 m/s at a certain temperature. at the same temperature, find the velocity of an oxygen molecule. what is the molar mass of a gas that diffuses 2.16 times faster than xenon? what diatomic element is it?

Answer 1

How do you calculate the rate of effusion of h2?

From Graham's law, we can use the molar mass of each gas: rate of effusion of hydrogenrate of effusion of oxygen=√32g mol−1 √2g mol−1 =√16√1=41 rate of effusion of hydrogen rate of effusion of oxygen = 32 g mol − 1 2 g mol − 1 = 16 1 = 4 1 Hydrogen effuses four times as rapidly as oxygen.
