"mol is the amount of substance in a system, and the number of structural particles contained in the system is equal to the number of atoms of 0.0 12kg carbon-12. When using mol, structural particles should be specified, which can be atoms, molecules, ions, electrons and other particles, or a specific combination of these particles. "
Therefore, the mole is the unit of the quantity of matter. The number of microscopic particles such as molecules or atoms in 1mol is Avogadro constant, which is the 23rd power of 6.02× 10.
1 mol = 1000 mmol.
1 mmol = 1000 micromoles (μmol)
1 micromole (μmol) = 1000 nanomole (nmol)
1 mmol = 1000 mmol.
