how many atoms are in 14 moles of cadmium?

atoms are in 14 moles of cadmium.

Explanation:

Cadmium is a white and  silvery  metal  that is found in the curst of the earth.During the  production process of metals such as lead, copper, zinc, cadmium is extracted

Cadmium is present in some foods and is emitted when fossil fuels like as coal and oil is used, smoking cigarettes. It is used in craft glazes, metal batteries, and coatings.

We know that 1 mole of  Cadmium (Cd contains) 6.023*1023 atoms, which is Avogadro's number.

So in 14 Grams of Cadmium, the number of atoms present is,

=>14×number atoms present in one cadmium atom

=>

=>

The number of atoms of Cadmium present in 14 moles is 84.322   atoms.

The number of atoms in a mole of compounds can be given by the Avagadro number. The Avagadro number has been equal to 6.023

Thus, 1 mole =  6.023 atoms

The given element has been Cadmium. The moles of Cadmium is 14 moles.

By simplifying with unitary method:

1 mole =  6.023 atoms

14 moles = atoms

14 moles of Cadmium = 84.322 atoms.

The number of atoms of Cadmium present in 14 moles is 84.322   atoms.
