Two vessels are connected by a valve. One contains 10 g of $H_2$ at 27°C and 1 atm. The other contains 16 g of $O_2$ at 27°C and 1 atm. If the valve is opened and the gases mix completely, what is the partial pressure of $H_2$ in the mixture (assuming ideal behavior)?

Equal moles of hydrogen and oxygen gases are placed in a container with a pin-hole through which both can escape. What fraction of the oxygen escape in the time required for one-half of the hydrogen to escape?

Equal moles of hydrogen and oxygen gases are placed in a container with a pin-hole through which both can escape. What fraction of the oxygen escape in the time required for one-half of the hydrogen to escape?

A certain gas takes 3 times as long effuse out as Helium. Its molecular mass will be

$2{\rm{g}}$ of hydrogen diffuses from a container in 10 minute. How many gram of oxygen would diffused through the same container in the same time under similar conditions?

Two gases, A and B, have molar masses of 2 g/mol and 32 g/mol respectively. According to Graham's Law, what is the ratio of their rates of effusion?

Equal moles of nitrogen and oxygen gases are placed in a porous container. After a certain time, one-fifth of the nitrogen has escaped. What fraction of the oxygen has escaped in the same time period?

The root mean square speed of hydrogen molecules at room temperature is $2400\,\,{\rm{m}}{{\rm{s}}^{ - 1}}$. At room temperature the root mean square speed of oxygen molecules would be:

Identify the pair of gases that have equal rates of diffusion

If gas X effuses twice as fast as gas Y, what is the ratio of their molar masses?

A porous barrier separates two chambers containing equal volumes of $He$ and $CH_4$ at the same temperature and pressure. After a certain time, it's observed that 1/4 of the $He$ has effused. Approximately what fraction of the $CH_4$ has effused during the same time?
