MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

According to Henry's law, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. S = K_H P Given: K_H = 3.0 10^ -2 mol dm ^ -3 atm ^ -1 P = 3 atm Substituting the values: S = (3.0 10^ -2 mol dm ^ -3 atm ^ -1 ) 3 atm S = 9.0 10^ -2 mol dm ^ -3 Since 1 mol dm ^ -3 = 1 M , the solubility is 0.09 M . Answer: 0.09 M
