Mixtures and Alligation

If $X_m, X_p$ and $X_v$ are mole fraction, pressure fraction and volume fraction respectively for a gaseous component in mixture. Select the correct relationship between them.

A container contains the mixture of water vapour and oxygen gas with total pressure 1.1 atm at a certain temperature. If the volume is made one third then the total pressure will be: [Assume aqueous tension of water at this temperature is 0.1 atm.]

In a gaseous mixture at $20^{o} C$ the partial pressure of the component gases are as follows: hydrogen 200 mm, carbon dioxide 150 mm, methane 320 mm, ethylene 130 mm. Volume fraction of hydrogen is __________.

For the following equilibrium reaction, $N_{2}O_{4}(g) \rightleftharpoons 2NO_{2} (g)$ $NO_{2}$ is $50\%$ of the total volume at a given temperature. Hence vapour density of the equilibrium mixture is:

$90 \%$ acid solution $(90 \% $pure acid and $10 \ $ water) and$ 97 \%$ acid solution are mixed to obtain $21 $ litres of $95\%$ acid solution. How many litres of each solution are mixed?

One litre of oxygen at a pressure of $1 atm$ and two litres of nitrogen at a pressure of $0.5 atm$, are introduced into a vessel of volume $1 L$. If there is no change in temperature, the final pressure of the mixture of gas (in atm) is

$60$ % of $H_{2}$ and $40$% of $O_{2}$ by volume are present in a mixture at a pressure of $100$ $mm$. Pressure exerted by $H_{2}$ is:

Two glasses of equal volume are respectively half and three-fourths filled with milk. They are then filled to the brim by adding water. Their contents are then poured into another vessel. What will be the ratio of milk to water in this vessel?

$520\ g$ of tiny pink pebbles are mixed with $580\ g$ of tiny purple pebbles. Vihan packed the mixture of the tiny pebbles into $5$ equal packets. How many grams of the mixture are there in each packet?

A mixture of 40 liters contains wine and water in the ratio of 3:1. How much water must be added to the mixture so that the ratio of wine and water is 5:2 ?

A mixture contains alcohol and water in the ratio $4 :$3. If $5 litres$ of water is added to the mixture, the ratio becomes $ 4: 5 .$ Find the quantity of alcohol in the given mixture .

A $16$ quart radiator is filled with water. Four quarts are removed and replaced with pure antifreeze liquid. Then four quarts of the mixture are removed and replaced with pure antifreeze. This is done a third and a fourth time. The fractional part of the final mixture that is water is:

Choose the most appropriate option. $60$kg of an alloy X is mixed with $100$ kg of an alloy Y. If alloy X has lead and tin in the ratio of $3:2$ and alloy Y has tin and copper in the ratio of $1:4$, then the amount of tin in the new alloy is?
