If 1.23 g of chlorine gas dissolves in
0.95 L of water at 15.6 psi, at what
pressure (in psi) would you be able
to dissolve 1.89 g in the same
amount of water?

The pressure : 23.48 psi

Henry's Law stated that the solubility of a gas is proportional to its partial pressure  

Can be formulated  

S = kH. P.  

S = gas solubility, mol / L  

kH = Henry constant, mol / L.atm  

P = partial gas pressure  

MW Cl₂ = 71 g/mol

mol of 1.23 g Cl₂ :

Solubility O₂ : 0.017 mol/0.95 L =0.01789 mol/L

Henry's constant for O₂ :

P = 15.6 psi= 1.061517 atm

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
