Assume that the headspace volume of a bottle of soda is 15 mL, the water volume is 355 mL water, and the total weight of CO2 in the headspace is 0.20 g. Henry's law constant for CO2 at 20C is 3.5x10-2 mol/(L atm). The Ka value of carbonic acid is 4.3x10-7. (a) What is the pressure inside a bottle of soda? The answer for (a) is ---atm. (answer format: ?.?) (b) what is the concentration of CO2 in water? The answer for (b) is ---M. (answer format: ?.??) (c) what is the weight of CO2 in water? The answer for (c) is ---g. (answer format: ?.?) d) what is the pH of carbonated water? The answer for (d) is ---. (answer format: ?.?)
