The statement “If 0.003 moles of a gas are dissolved in 900 g of water under a pressure of 1 atmosphere, 0.006 moles will be dissolved under a pressure of 2 atmospheres”, illustrates [JIPMER 1999] (a) Dalton’s law of partial pressure (b) Graham’s law (c) Raoult’s law (d) Henry’s law
Correct option is D) Henry's law is one of the gas laws states that: at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. from question 0.003 moles of gas is dissolved in 900g of water under a pressure of 1 atm 0.006 moles will be dissolved under a pressure of 2 atmospheres. clearly it can be seen that no. of mole dissolved is directly proportional to partial pressure. thus, the correct answer is D.
