what is the relationship between mole and avogadro number?

One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan.

A modern statement is: Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

1 Answer. Alexander A. A mole is 6.02⋅1023 (avogadro's number) molecules of a substance. The molar mass is the amount of mass that 1 mole of that substance possesses.

In order to have one mole of things, let's say particles, you need to have 6.022⋅1023 particles → this is known as Avogadro's constant and acts as the definition of the mole. So, in one mole of nitrogen gas you have 6.022⋅1023 molecules of nitrogen gas, N2 .

Avogadro's number: The number is 6.022 x 10^23 atoms/mol. So, if you have 1 mole of carbon atoms, there will be 6.022 x 10^23 atoms in that sample.

Explanation: Recall that moles can be converted to particles using Avogadro's constant ( 6.022⋅1023 ) which is the number of molecules per mole of a substance. In 1.5 moles of fluorine gas, there are 1.5⋅6.022⋅1023 molecules of gas.

To calculate the number of atoms in a sample, you need to find how many moles of the element the sample contains. A mole is a unit chemists use. It's equal to Avogadro's number (6.02 X 1023) of atoms. By definition, the weight of one mole of an element (its molar mass) is equal to its atomic weight in grams.

One mole of a substance contains the same number of particles as one mole of any other substance. The particles can be atoms, molecules or ions. The number of atoms, molecules or ions in one mole of a substance is called the Avogadro constant . ... The number of chloride ions in 1 mol of sodium chloride is also the same.

In your case, a mole of methane represents a collection of methane molecules. More specifically, a mole of methane contains 6.022⋅1023 molecules of methane - this is known as Avogadro's number.

Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

One mole of atoms contains 6 x 10 23 atoms, no matter what element it is. This is a very large number: it is 6 with 23 zeros after it. It is known as the Avogadro number. This number is used in chemistry because if you could count out this many carbon atoms, the total mass of carbon you would have is 12 g.

The mole. Chemists measure the amount of a substance in a unit called 'the mole'. ... It allows chemists to make predictions about the masses of different substances that are involved in reactions. One mole is the Avogadro number of particles (atoms, molecules , ions or electrons ) in a substance.

One mole of anything is 6.022 x 10^23 particles. That's what a mole is and 6.022 x 10^23 is the Avogadro number. So, 1 mole of electrons is 6.022 x 10^23 electrons.

Avogadro's number states that one mole of any substance contains 6.022 * 1023 number of atoms. That means 1 mol of Helium, 1 mole of Copper, 1 mol of gold, and 1 mol of Aluminum, all contain 6.022 * 1023 number of atoms.

Explanation: The key here is Avogadro's constant, which tells you the number of representative particles present in 1 mole of a substance. By definition, and this is what Avogadro's constant tells you, 1 mole of nickel must contain 6.022⋅1023 atoms of nickel.

Avogadro's Law is stated mathematically as follows: Vn=k, where V is the volume of the gas, n is the number of moles of the gas, and k is a proportionality constant.

Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA.
