On the unit of amount of substance

2009-08-08View Original

Thread Content

I recently found some key data, but the units are not standard. I would like to know the relationship between Kgmol, gmol, and mol. Thank you!

kg mol = 1000 g mol = 1000/M mol, where M is the molecular weight of the substance

The first two don’t seem to be units of amount of substance; kgmol refers to kg/mol, while gmol refers to g/mol. These are actually units of molar mass, that is, the weight of 1 mole of a substance

kg mol = 1000 g mol = 1000/M mol, where M is the molecular weight of the substance. In some sources, the units used are not standard.

In Kgmol and gmol, there is a missing “/” symbol; it indicates how much weight each mole of the substance has. The units kg and g represent the molecular weight of the substance, while mol denotes the number of moles of that substance, which is obtained by dividing the mass of the substance by its molecular weight.

The unit of amount of substance is (mol); in science, a collection containing 6.02×10²³ particles is considered as one unit, called a mole. Mole is the unit used to express the amount of substance (denoted by the symbol n); it is abbreviated as mol, with the unit symbol being mol. The 14th General Conference on Weights and Measures in 1971 provided the following two provisions regarding the definition of mole: “A mole is the amount of substance in a system whose number of elementary units is equal to the number of atoms in 0.012 kg of carbon-12.” ”“When using moles, it should be specified what the basic unit is; this can be atoms, molecules, ions, electrons, and other particles, or specific combinations of these particles. ” The unit of mass is kg; 1 kg = 1000 g. The unit of molar mass is kg/mol or g/mol, with 1 kg/mol = 1000 g/mol. The mass of one mole of a substance is called its molar mass, denoted by the symbol M. When the mass of a substance is expressed in grams, the unit for molar mass is g/mol, and this value is numerically equal to the relative atomic mass or relative molecular mass of that substance. Since the mass of molecules or atoms in a substance is extremely small, it is measured in units of g/mol.

If the data is obtained from pro II, then Kgmol = kmol; gmol = mol
Reply #82009-08-08
kg mol is the same as kmol (kilomoles), and g mol is the same as mol (moles)
Reply #92009-08-08
1 KGmol = 1 kmol = 1000 gmol = 1000 mol

1# yanyu002 In many simulation calculations, such units appear: kg-mol=kmol, g-mol=mol

Basic knowledge of units like Kgmol, gmol, and mol~ kg/mol = kmol = 1000 g/mol = 1000 mol
