How many grams of water are required to dissolve $4 \ g$ of sodium sulfate at $323 \ K$? The solubility of sodium sulfate at this temperature is $16\%$.

For the solution of the gases $w$,$x$,$y$ and $z$ in water at $298 \ K$,the Henry's law constants $(K_H)$ are $0.5$,$2$,$35$ and $40 \ kbar$,respectively. The correct plot for the given data is

The quantity of $CO_2$ in $500 \ mL$ of soda water when packed under $3.34 \ bar$ $CO_2$ pressure at $298 \ K$ in $g$ is

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 $50 \ kbar$)

What type of solution is the $H_2$ gas in palladium?

The Henry's law constant for the solubility of $N_2$ gas in water at $25 \, ^oC$ is $1 \times 10^5 \, atm$. The mole fraction of $N_2$ in air is $0.8$. Calculate the number of moles of $N_2$ from air that will dissolve in $10 \, moles$ of $H_2O$ at $25 \, ^oC$ and at a total pressure of $5 \, atm$.
