$A$ gas '$X$' is dissolved in water at $2 \ bar$ pressure. Its mole fraction is $0.02$ in solution. The mole fraction of water when the pressure of gas is doubled at the same temperature is

Consider a solution of $CO_{2(g)}$ dissolved in water in a closed container. Which one of the following plots correctly represents the variation of $log$ (partial pressure of $CO_2$ in vapour phase above water) [y-axis] with $log$ (mole fraction of $CO_2$ in water) [x-axis] at $25^{\circ}C$?

$5.5 \text{ mg}$ of nitrogen gas dissolves in $180 \text{ g}$ of water at $273 \text{ K}$ and $1 \text{ atm}$ pressure due to nitrogen gas. The mole fraction of nitrogen in $180 \text{ g}$ of water at $5 \text{ atm}$ nitrogen pressure is approximately:

At $T(K)$,the partial pressure of dissolved oxygen in $1 \ L$ water is $1 \ bar$. The concentration of oxygen in $ppm$ is ($K_{H}$ of $O_2$ at $T(K)$ is $50 \ kbar$)

How many grams of carbon dioxide gas are dissolved in $1 \ L$ of carbonated water,if the manufacturer uses a pressure of $2.4 \ atm$ in the bottling process at $25^{\circ} C$ (in $g$)? ($K_{H}$ of $CO_2 = 3000 \ atm$)

$1 \ g$ of silver gets distributed between $10 \ cm^{3}$ of molten zinc and $100 \ cm^{3}$ of molten lead at $800^{\circ} C$. The percentage of silver still left in the lead layer is approximately
