Question

If the partial pressure of CO2 is 2.87 atm the soluability in H2O is known to be 4.68 M. What would be the soluability of CO2 in H2O if the partial pressure is increased to 7.60 atm? Assume the temp is held constant.

would it work to set up a proportion for this question? if not, how should i set it up???

Answer 1

partial pressure CO2 = kc
Knowing p = 2.87 atm when c is 4.68 M allows k to be calculated. Then k and p can be used to calculate the new solubility (note spelling) in mola/L. Post your work if you get stuck.

Answer 2

thank you
