What type of solution is brass?

Which of the following statements is correct regarding Henry's law?

What is the solubility of a gas in water at $25^{\circ} C$ if the partial pressure is $0.18 \ atm$? $(K_{H} = 0.16 \ mol \ dm^{-3} \ atm^{-1})$

What kind of attractions are present in an aqueous solution of $NaCl$?

As temperature increases,the value of $K_H$ increases,thus the value of solubility of a gaseous solute will $ . . . . . . $.

Maximum amount of a solid solute that can be dissolved in a specified amount of a given liquid solvent does not depend upon $ . . . . . . $ .
