I am attempting to use the Henderson Hasselbalch equation to calculate the pH of blood with a pCO2 of 41mmHg and a bicarb concentration of 20mM. I know how to do this problem but was not sure if I needed to convert mmHg to mM in order for the equation to work. I have been looking for conversion factors to do so but have been unsuccessful. Any suggestions are appreciated. Thanks.

You would normally do this by using the ideal gas law.

I did some more searching and it looks like you multiply the pCO2 concentration by .03 for some reason.

Search google or PubMed site. It's good to use graph or empirical equation, do not make your own conversion factor.

Combined solution solubility is not easy. Use graph or empirical equation.
