Orders of magnitude (molar concentration)

This page lists examples of the orders of magnitude of molar concentration. Source values are parenthesized where unit conversions were performed.

M denotes the non-SI unit molar:

1 M = 1 mol/L = 10−3 mol/m3.

11.04 g/l is the concentration of sodium ions in water in other words. That’s 1.09% sodium ion!

The concentration of hydronium ions in pire water is 1.9 micrograms per liter. That’s 1.9 parts per billion of hydronium.

The normal range for hemoglobin molecules is 254.36 grams per liter or 20.27% hemoglobin. The concentration of pure water is 1 kilogram per liter or 50% water. Glacial acetic acid is 1.05 kilograms per liter or 51.2% acetic acid.
