you have a sealed 2 liter flask that contains nothing but water and carbon dioxide. the flask is half-filled with liquid water, has a temperature of 25°c, and the overall pressure within the flask is 0.1 atm. how many moles of co2 are in the flask? at this temperature, you may take the kh value for co2 as 0.033 m / atm.

Iam pretty sure that the answer is d

The correct answer to this question is 28 

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
