The atmospheric concentration of CO2 gas is presently 390 ppm (parts per million, by volume; that is, 390 L of every 106 L of the atmosphere are CO2). What is the mole fraction of CO2 in the atmosphere?

The Henry's Law constant for CO2 at 25 C is 0.033363 mole/L-atm,the atmospheric CO2 content is 390 ppm calculate the concentrationof dissolved CO2 (in mol/L and in mgCO2/L) in a body of water whichis in equilibrium with the atmosphere

Given the concentration of CO2 in the atmosphere is 407 ppm (= 0.000407 mol fraction), determine the equilibrium concentration of CO2 in water, [CO2] at 10°C in mol/L.

Henry's constant for CO2 is: 0.104 E^-4 atm

For Part B, Your KH is 0.042 mol/(L*atm), K1=4.47 x 10-7, and K2= 4.68 x 10-11

B) If you have a pH of 8.2 and an atmospheric concentration of 280 ppm CO2 (which is a partial pressure of CO2 of 280 x 10-6 atm), what are your concentrations of [CO2](aq), and [HCO3-] and what is your total dissolved carbon (the sum of these two carbon ions) in mol/L. Recalculate this if your atmospheric concentration of CO2 is 400 ppm and pH is 8.1.

C) If there is 1.3 x 1021 L of water in the world's oceans, how much more carbon (in kg) can be stored in the oceans today at equilibrium (with 400 ppm CO2 in the atmosphere and ocean pH of 8.1) compared to pre-industrial revolution (when it was 280 ppm CO2 in the atmosphere and pH of 8.2). convert the mol/L in part B to kg C (0.012 kg C/mol C)
