Millimole, micromole, how to convert that mole?

The specific conversion method is as follows:

1, 1 mol = 1000 mmol.

2. 1 mmol = 1000 μmol.

3. 1 micromole (μmol) = 1000 nmol.

4. 1 mmol = 1000 mmol.

5、 1 1 mmol/L = 1000 μm ol/L = 1000000 nmol

Mol, referred to as Mo for short, used to be called Mol and gram atom, and the symbol is MOL, which is the unit of matter and one of the seven basic units of the International System of Units. Every 1 mole of any substance (micro-substance, such as molecules and atoms) contains Avon Garderot constant (about 6.02× 10? ) particles.

When using moles, the basic particles should be specified, which can be atoms, molecules, ions and other microscopic particles, or a specific combination of these microscopic particles.

About 6.02× 10? One is 1 mole, just like people often say that a dozen is 12, and "mole" is just a special unit like "dozen". 0.0 12kg ( 12g)？ C (carbon 12) contains atoms of 1 mol.

Expand the development history of data Moore

Moore is the seventh basic unit of the International System of Units (SI), which is 197 10 international metrology conference plus 4 1 country. Mole is used to calculate the number of particles, the mass of matter, the volume of gas, the concentration of solution, the change of heat during the reaction and so on. Moore comes from the Latin moles, which means to accumulate a lot.

197 1 The 14th International Metrology Conference defined the mole in the following two paragraphs: "Mole is the amount of substances in a system, and the number of basic units contained in this system is equal to the number of atoms in 0.0 12kg carbon-12."

"When using moles, you should specify the basic unit, which can be atoms, molecules, ions, electrons and other particles, or a specific combination of these particles."

The last two paragraphs should be regarded as a whole. The number of carbon atoms in 0.0 12kg carbon-12 nuclide is Avogadro constant (NA). At present, the approximate value measured in the experiment is NA=6.02× 10? .

Moore is different from ordinary units, it has two characteristics:

① Measurement of microscopic basic units, such as molecules and ions, cannot be used to measure macroscopic substances.

(2) it takes Avon Gadereau number as the unit of measurement, and it is a batch, not a number, to measure the number of particles such as molecules and atoms. It can also be used to measure the specific combination of microscopic particles. For example, the amount of sulfuric acid is measured by moles, that is, 1mol sulfuric acid contains 6.02× 10? One molecule of sulfuric acid.

Molar is the most widely used unit of measurement in chemistry, such as calculation of chemical reaction equation, calculation in solution, preparation and dilution of solution, calculation of chemical equilibrium, molar volume of gas, thermochemistry and so on.
