Mixtures and Alligation

At constant temperature $ N_2 $ gas of 200 cm at 720 mm pressure and $ O_2 $ gas of 400 $ cm^3 $ at 750 mm pressure. These are mixed in 1 ltr capacity flask, than what will be the final pressure.

A 3L container at 3 atm pressure consist a mixture of $N_2$ gas and $H_2O$ vapours. Solid sphere of volume 0.5L is also present in same container. What will be the pressure of gas, if volume of container is reduced to 2L, at same temperature (AQ. tension = 0.2 atm)?

$2\ g$ of gas $A$ introduced in a evacuated flask at $25^{o}C$. The pressure of the gas is $1$ atm. Now $3\ g$ of another gas $B$ added to the same flask, the pressure becomes $1.5$ atm. The ratio of molecular mass of $A$ and $B$ is

Gaseous mixture of contains $56g$ of ${ N }{ 2 },$ $44g$ of ${ CO }{ 2 }$ and $16g$ of ${ CH }{ 4 }.$ The total pressure of mixture is $720atm$ of $Hg$ The partial pressure of ${ CH }{ 4 }$ is:

A methane + $H_2$ mixture contains 10 g methane and 5 g Hydrogen. If the pressure of the mixture is 30 atm. What is the partial pressure of $H_2$ in mixture.

${\text{8}}\,{\text{gm}}$ of ${{\text{H}}{\text{2}}}$ and ${\text{32}}\,{\text{gm}}$ of ${\text{S}}{{\text{O}}{\text{2}}}$ are present in a gaseous mixture at ${\text{NTP}}$. The partial pressure of ${{\text{H}}_{\text{2}}}$ is

If $H_2$ and $Cl_2$ enclosed separately in the same vessel exert pressures of $100$ and $200$ mm respectively, their mixture in the same vessel at the same temperature will exerts a pressure of $300$ mm.

Equal masses of $SO_{2}$ and $O_{2}$ are kept in a vessel at $27^{o}C$. The total pressure of the mixture is 2.1 $atm$. The partial pressure of $SO_{2}$ is:

In a ten litre vessel, the total pressure of a gaseous mixture containing $H_{2}, N_{2}$ and $CO_{2}$ is $9.8$ $atm$. The partial pressures of $H_{2}$ and $N_{2}$ are $3.7$ and $4.2$ $atm$, respectively. The partial pressure of $CO_{2}$ is:

At atmospheric pressure, a litre vessel contains a mixture of Helium and Nitrogen. If partial pressure of Nitrogen is 500 mm, the partial pressure of Helium will be:

A cylinder contains 0.3 mole $N_{2}$, 0.1 mole $O_{2}$ and 0.1 mole $He$. If the total pressure of gas mixture is 1 atmosphere, the partial pressure of $O_{2}$ in $mm$ of $Hg$ is:

A gaseous mixture contain 56 grams of N 2 , 44 grams of C O 2 and 16 grams of C H 4 . The total pressure of the mixture is 720 m m H g . The partial pressure of C H 4 is:

The total pressure of a mixture of 6.4 grams of oxygen and 5.6 grams of nitrogen present in a 2 litre vessel is 1200 $mm$. What is the partial pressure ( in $mm$ ) of nitrogen?
