MHT-CET Physics and Chemistry Full Test-7 CHE-Que-32 Solution

Q.32. What is the solubility of gas in water at 25^∘C if partial pressure is 0.346 bar [Henry’s law constant is    [0.159 mol dm⁻³ bar⁻¹] ?

A  0.055 mol dm⁻³

B  0.028 mol dm⁻³

C  0.083 mol dm⁻³

D  0.11 mol dm⁻³

Answer :- A  0.055 mol dm⁻³

Explanation :-

S=K_HP =0.159 mol dm⁻³ bar⁻¹× 0.346 bar

= 0.055 mol dm⁻³
