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)?

$2{\rm{g}}$ 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?

50 mL of hydrogen diffuses through small hole from a vessel in 20 min. Time taken for 40 mL of oxygen to diffuse out under similar conditions 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?

$A$ , $B$ and $C$ are ideal gases. Their molecular weights are 2, 4 and 28 respectively. The rate of diffusion of these gases follow the order

What is the ratio of diffusion rate of oxygen and hydrogen?

Identify the pair of gases that have equal rates of diffusion

Which pair of the gases diffuse through a small hole with the same rate of diffusion at same ‘P’ at ‘T’

The rate of diffusion of hydrogen gas is

Diffusion of helium gas is four times faster than

When $r,p\,\,{\rm{and}}\,\,M$  represent rate of diffusion, pressure and molecular mass, respectively, then the ratio of the rates of diffusion $\left( {{r_A}/{r_B}} \right)$ of two gases $A\,\,{\rm{and}}\,\,B$  is given as
