Hi, I am currently finishing a lab and am stuck on the last question on my write up.  It is asking me to derive the value of R (Universal Gas Constant) from mL-mmHg mol^-1K^-1.  While I am able to do this in standard units, L and atm the numbers don't seem to function properly with the above listed.  Any help would be much appreciated.  Thank you very much.

Are you trying to convert the gas constant from L.atm.K-1.mol-1 to mL.mmHg.mol-1.K-1? If so you really just need to convert L to mL and atm to mmHg.

PV = nRT

R = PV/nT where
P: pressure, mmHg
V: volume, ml
n: moles, mol
T: temperature, K

Put data for STP and 1 mole  to equation for R  in proper units


R = PV/nT =  760 mmHg x 22400 mL/(1mole x 273.15 K) =
