pptM is "parts-per-trillion by Molar"
If possbile, can anybody explain pptM using example?
For example, pptM is equal to ..........ppbM.
Thank you for your help.

Moles of benzene in moles of nitrogen. 1 mole of N2 being approx 22.4 L of gas. Used in gas phase work all the time.

In SI units that are universally understood and readily interchangeable pptM is equivalent to pmol/mol, and ppbM is equivalent to nmol/mol. They are mole fractions and within the limits of the gas law also volume fractions.
