Question

Choose the most correct option.

Henry’s law constant for a gas CH3Br is 0.159 mol dm^-3 atm^-1 at 25 °C. What is the solubility of CH₃Br in water at 25 °C and partial pressure of 0.164 atm?

विकल्प

• 0.0159 mol L^-1

• 0.164 mol L^-1

• 0.026 M

• 0.042 M

Answer 1

0.026 M

Explanation:

S = K_HP = 0.159 mol dm^-3 atm^-1 × 0.164 atm

= 0.026 M
