Henry's constant (in kbar) for four gases , ,  and  in water at 298 K is given below:

| |  |  |  |  |
|---|---|---|---|---|
|  | 50 | 2 |  | 0.5 |

(density of water =  kg m⁻³ at 298 K)

Strategy:
 Henry's law constant () inversely relates to solubility. For a given pressure, the gas with the lowest  will have the highest mole fraction (solubility). We also check the pressure for a 55.5 molal solution (which means ).

Step 1: Evaluate Statement (3)
The statement mentions a 55.5 molal solution of .
- 55.5 mol of solute per 1 kg (55.5 mol) of water.
- Mole fraction .
Using Henry's law  for  ():

This matches statement (3) exactly.

Step 2: Determine why other statements are incorr
