Dr BOB can you explain this to me. I am so struggling with this subject.
during a typical breathing cycle the CO2 concentration in the expired air rises to a peak of 4.6% by volume. Calculate the partial pressure of the CO2 at this point, assuming 1 bar of pressure. what is the molarity of the CO2 in the air at this point, assuming body temp is 37 degreesC.
any help will do?
