|Value of NA in various units|
The Avogadro constant (symbols: L, NA) is the number of particles (usually atoms or molecules) in one mole of a given substance. Its value is equal to 6.02214129(27)×1023 mol−1. The constant was named after the ItalianscientistAmedeo Avogadro.
Avogadro’s number is 6.022 x 10 23. It is the value given for the Avogadro’s Constant. The same thing represented by the Avogadro’s number was first calculated by a German scientist Johann Loschmidt but in different units. Updated January 05, 2019 Avogadro's number is one of the most important constants used in chemistry. It is the number of particles in a single mole of a material, based on the number of atoms in exactly 12 grams of the isotope carbon-12.

Nae caulom 27. Here is the answer for the question – Avogadro’s Number or NA. You’ll find the correct answer below Avogadro’s Number or NA The Correct Answer is 6.02×10^23Ex: 3 mol carbon x 6.02 x 10^23/ 1 mol C atoms Reason Explained 6.02×10^23Ex: 3 mol carbon x 6.02 x 10^23/ 1 mol C atoms is correct for.
The measurement of Avogadro's constant was refined in 2011 to 6.02214078×1023 ± 0.00000018×1023.
An old term closely related to the Avogadro constant is Avogadro's number. Avogadro's number is the number of atoms in 12 grams of the carbonisotopecarbon-12. Avogadro's number is a dimensionless quantity and has the numerical value of the Avogadro constant given in base units.
