## O2 conversion

The molar volume of an ideal gas is ~22.4 liters per mole (we’ll consider O2 to be an ideal gas for these purposes, and 22.4 is an approximation that varies with temperature, it’s 22.414 at 0C). Convert from 22.4 liters to milliliters ( = 22400 ml per mol). So if you have 1 milliliter of an ideal gas, there is 1 ml / 22400 ml per mol = 0.00004464 mol of that gas, which is 44.64 µmol of the gas. Thus, if you have a volume of a gas in ml, you can calculate the µmols of that gas simply … Continue Reading
