How Many Molecules are contained in 0.25 moles of Fe?

1 mol contains 6.02 x 10^23 molecules.

So 0.25 mols will contain 0.25 x 6.02 x 10^23 molecules.

To calculate the number of molecules contained in 0.25 moles of Fe (iron), we can use Avogadro's number.

Avogadro's number is defined as 6.022 x 10^23 molecules per mole.

To find the number of molecules, we multiply the number of moles by Avogadro's number:

Number of molecules = 0.25 moles x 6.022 x 10^23 molecules/mole

Number of molecules = 1.5055 x 10^23 molecules

Therefore, there are approximately 1.5055 x 10^23 molecules in 0.25 moles of Fe.

To find out how many molecules are contained in 0.25 moles of Fe (iron), we need to use Avogadro's number.

Avogadro's number, represented by the symbol "Nā‚," is a fundamental constant in chemistry that represents the number of particles (atoms, molecules, ions) in one mole of a substance. The value of Avogadro's number is approximately 6.022 x 10^23.

To determine the number of molecules in 0.25 moles of Fe, we can use the following equation:

Number of molecules = Number of moles x Avogadro's number

Substituting the known values:

Number of molecules = 0.25 moles x 6.022 x 10^23

Calculating the result:

Number of molecules = 1.5055 x 10^23

Therefore, there are approximately 1.5055 x 10^23 molecules in 0.25 moles of Fe.
