HELP ME WITH THIS ONE WHEN DONE WITH THE OTHER THX
calculate the concentration of CO2 in a soft drink after the bottle is opened and equilibrates at 25C under a CO2 partial pressure of 0.0003 atm.

c=KP henry's law

k=?

k for CO2 is 3.4E-2 mols/L*atm
c=KP
Substitute p of 3.4E-2 for K and 3E-4 for P, solve for C (in M or mols/L)
P=0.0003 atm. how to solve

not getting answer of 9.3E-6 M

help me

Don't swith screen names.
Your other post says answer is 0.976E-6M
You need to find out what your teacher used for K; in fact, s/he should have given it to you. A K of 3.1E-2 mol/L*atm will give you 9.3E-6M

no she didn't give it sadly

thanks
