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?
Options
0.0159 mol L-1
0.164 mol L-1
0.026 M
0.042 M
Solution
0.026 M
Explanation:
S = KHP = 0.159 mol dm-3 atm-1 × 0.164 atm
= 0.026 M
