Henry's law constant for CO2 in the water at 25°C is 3.1 * 10^-2 M atm^-1.

a. What is the solubility of CO2 in the water at this temperature if the solution is in contact with air at normal atmospheric pressure? The mole fraction of CO2 in the air is 0.000375. Express your answer using two significant figures.

b. Assume that all of this CO2 is in the form of H2CO3 produced by the reaction between CO2 and H2O:

CO2 (aq) + H2O (l) => H2CO3 (aq).

What is the pH of this solution? Express your answer using two decimal places.
