Calculate the concentration of CO 2 in a soft drink, which is bottled with a partial pressure of CO 2 of 4 atm over the liquid at 25 ° C . The Henry's law constant for CO 2 in water at 25 ° C is 3 . 1 × 10 - 2 mol L - 1 atm - 1 .

According to Henry's law, C = Pk H Whereas, C = Concentration of gas in mol L - 1 P = Partial pressure of gas in atm k H = Henry's constant in mol L - 1 atm - 1 Now, C = 3 . 1 × 10 - 2 × 4 = 0 . 124 mol L - 1
