Which of the following laws represents the quantitative relationship between the solubility of gas in liquid and its pressure?

What happens when a saturated solution of sugar is heated?

The Henry's law constant for the solubility of $N_2$ gas in water at $298 \ K$ is $1.0 \times 10^5 \ atm$. The mole fraction of $N_2$ in air is $0.8$. The number of moles of $N_2$ from air dissolved in $10 \ moles$ of water at $298 \ K$ and $5 \ atm$ pressure is

Explain the solubility rule "like dissolves like" in terms of inter-molecular forces that exist in solutions.

In which of the following salts,the solubility increases appreciably with an increase in temperature?

$H_2S$,a toxic gas with rotten egg like smell,is used for the qualitative analysis. If the solubility of $H_2S$ in water at $STP$ is $0.195 \, m$,calculate Henry's law constant.
