If The Atomic Mass Of An Element Is X, What Is The Mass In Grams Of 6.02×1023 Atoms Of The Element?

Qthe solution is: 6.02 x 1023xg atoms or simply xg atoms.  Heres the explanation.

The amount of a substance in chemistry is measured using a unit called ‘the mole’. It is used to conveniently count atoms. Atoms help in calculating the masses of different substances that are involved in chemical reactions.

The atomic weight of each element is listed in the periodic table. To describe the mass of atoms, scientists use Atomic Mass Units (AMU).

The number 6.02 x 1023 is popularly known as Avogadro’s constant or Avogadro’s number.

Accordingto this concept, the number of units in one mole of any substance is equal to 6.02214076 x 1023. In other words, it is defined as the molecular weight in grams of that substance. This unit can be electrons, molecules, ions, or atoms depending on the character of the reaction (if any) and the nature of the substance.

Dealing with a single molecule or atom is impossible in chemistry because they cannot be weighed, seen, or counted. So, scientists select several particles to make the process convenient. Molecules are extremely small. Thus, scientist select a group of particles, which is 6.02 x 1023. The name of this group is known as mole or simply mol.

Now, we can solve the above problem by using Avogadro’s number. Here, the atomic mass of an element is x. We have to find out the mass in grams of 6.02 ×1023 atoms of the element.

One mole = 6.02 x 1023 atoms

Thus, the solution is: 6.02 x 1023xg atoms or simply xg atoms.
