Henry's law states that

the volume of gas that will dissolve in a solvent is proportional to the solubility of the gas and the gas pressure.
gas volume and pressure are inversely proportional.
gas volume and temperature are directly proportional.
in a mixture of gases such as air, the total pressure is the sum of the individual partial pressures of the gases in the mixture.
gas pressure is inversely proportional to gas volume.

The correct answer is: the volume of gas that will dissolve in a solvent is proportional to the solubility of the gas and the gas pressure.

That is correct! Henry's law states that the volume of gas that will dissolve in a solvent is proportional to the solubility of the gas and the gas pressure. This means that as the pressure of a gas increases, more of it will dissolve in the solvent. Conversely, as the pressure decreases, the amount of gas that dissolves will also decrease.

Gas volume and pressure are inversely proportional. This means that as the pressure of a gas increases, the volume it occupies will decrease, and vice versa.

Gas volume and temperature are directly proportional. According to the gas laws, as the temperature of a gas increases, its volume will increase, and as the temperature decreases, the volume will also decrease. This relationship is known as Charles's law.

In a mixture of gases such as air, the total pressure is the sum of the individual partial pressures of the gases in the mixture. This is known as Dalton's law of partial pressures. Each gas in the mixture exerts its own pressure, known as its partial pressure. The total pressure is the sum of all these partial pressures.

Lastly, gas pressure is inversely proportional to gas volume. This is Boyle's law, which states that as the volume of a gas decreases, its pressure will increase, and as the volume increases, the pressure will decrease.
