What is the relationship between Avagado's number and a mole?

Answer 1

1 mole of a substance contains 6.02 x 1023 particles (molecules, atoms ...). This number (6.02 x 1023) is called the Avogadro's constant. the forumula: n = N / NA (NA is the Avogadro's number / constant; N = number of particles (molecules, atoms...) in the substance)

Answer 2

A mole is Avogadro's number of molecules (or, for non molecular substances, atoms or formula masses instead of molecules). This number has been determined experimentally to be about 6.022 x 1023 molecules. A mole of any pure molecular chemical substance is 6.022 x 1023 molecules of that substance.

-----------------------------------------------------------------------------------------------

Imagine that you were able to count the atoms in exactly 12 grams of pure carbon-12, which has been defined to have a gram Atomic Mass of exactly 12. If you could, then it would come to 6.023*1023. If you could take 44 g, the gram molecular mass of CO2 gas, and count the number of molecules, it would be about 6.023*1023. 238 g, the approximate gram atomic mass, of uranium would have 6.023*1023 atoms.

These values of 12g, 44g and 238 g are known as one gram mole of carbon, carbon dioxide and uranium respectively.

The phrases "gram mole", "gram atomic mass", and "gram formula mass" should always be considered as single compound nouns, and any number preceding them applies to the phrase rather than to the single word "gram" with which the phrase begins.

Answer 3

Avogadro' Number, 6.0221367 X 1023 is the number of Molecules in 1 Gram Mole of a substance. One gram mole of Oxygen (at. no.16, at. wt. 32) has a mass of 32.00 grams and contains 6.0221367 × 1023 molecules.

The volume of one gram-mole of gas is about 22.4 l (0.791 cu. ft.) at standard temperature and pressure (0° C, 1 ATM) This is true for all gases.

Answer 4

Avogadro's number is the number of anything in a mole of that thing, which is 6.022 x 1023. For example, one mole of anything is 6.022 x 1023 of that thing, whether it be cars, shoes, or atoms, or molecules.

Answer 5

Avogadro's number is the number of atoms, molecules, or formula units in one mole of a substance. It is approximately 6.022 x 10^23, representing the number of particles in a mole. Avogadro's number allows scientists to make calculations and conversions between the macroscopic world and the microscopic world of atoms and molecules.

Answer 6

One mole contains Avogadro's number of 6.022 141 29 x 1023 particles.

Answer 7

A mole contains an avogadros number of molecules, formula units for chemical compounds or atoms for elements.
