Using the Molar Mass Calculator
- Chemical formulas should be filed case sensitive
- The index is entered as a regular number
- For example, in formulas for crystalline hydrates, the point used at the midline (multiplication sign) is replaced by a regular point.
- Example: Instead of CuSO₄ 5H₂O, the converter uses the spelling CuSO4.5H2O for ease of entry.
MOLAR MASS CALCULATOR
MOLE
All matter is made up of atoms and molecules. In chemistry, it is important to accurately measure the mass of substances that enter and result in a reaction. By definition, the mole is the SI unit for the amount of a substance. One mole contains exactly 6.02214076×10²³ elementary particles. This value is numerically equal to the Avogadro constant NA when expressed in units of moles⁻¹ and is called the Avogadro number. The amount of matter (symbol N ) is a measure of the number of structural elements of a system. A structural element can be an atom, a molecule, an ion, an electron, or any particle or group of particles.
Avogadro’s constant NA = 6.02214076×10²³ mol⁻¹. Avogadro’s number is 6.02214076×10²³.
In other words, the mole is equal to the mass of a substance, which is equal to the sum of the atomic masses of the atoms and molecules of the substance, multiplied by the Avogadro number. The mole is one of the seven basic units of the SI system and is represented by the mole. Since the name of the unit and its symbol are the same, it should be noted that the symbol is not inflected, unlike the name of the unit, which can be rejected according to the general rules of the Russian language. One mole of pure carbon-12 is equal to exactly 12 grams. (Molar Mass of H2O)
MOLAR MASS
Molar mass is a physical property of a substance, defined as the ratio of the mass of that substance to the amount of the substance in moles. In other words, it is the mass of one mole of a substance. In the SI system, the unit of molar mass is kilogram/mole (kg/mole). However, chemists are used to using the more convenient unit g/mol.
molar mass = g/mol
MOLAR MASS OF ELEMENTS AND COMPOUNDS
Compounds are substances made up of different atoms that are chemically bonded to each other. For example, the following substances, which can be found in the kitchen of any housewife, are chemical compounds:
- Salt (sodium chloride) NaCl
- Sugar (Sucrose) C₁₂H₂₂O₁₁
- Vinegar (acetic acid solution) CH₃COOH
The molar mass of chemical elements in grams per mole is numerically the same as the mass of the element’s atoms, expressed in atomic mass units (or daltons). The molar mass of a compound is equal to the sum of the molar masses of the elements that make up the compound, taking into account the number of atoms in the compound. For example, the molar mass of water (H₂O) is approximately 1 × 2 + 16 = 18 g/mol.
MOLECULAR MASS
Molecular mass (the old name is molecular weight) is the mass of a molecule, calculated as the sum of the mass of each atom multiplied by the number of atoms in this molecule. Molecular weight is a dimensionless physical quantity numerically equal to the molar mass. That is, the molecular weight differs in dimension from the molar mass. Although molecular mass is a dimensionless quantity, it has a value called the atomic mass unit (amu) or dalton (da), and is roughly equal to the mass of a proton or neutron. The atomic mass unit is also numerically equal to 1 g/mol.
The molar mass is calculated as follows:
