Calculate moles of Fe in 5.22 X 10^22 atoms of Fe?

Chemistry

Setler [38]2 years ago

Answer:

The amount of moles of Fe in 5.22*10²² atoms of Fe is 0.0867.

Explanation:

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023*10²³ atoms are contained in 1 mole, 5.22*10²² atoms are contained in how many moles?

amount of moles=\frac{5.22*10^{22}atoms * 1 mole}{6.023*10^{23}atoms}

amount of moles= 0.0867

<u><em>The amount of moles of Fe in 5.22*10²² atoms of Fe is 0.0867.</em></u>
