Determine the number of atom in 5.0 moles in SI

3.01 x 10^24 atoms

Explanation:

Based on Avogadro's law:

1 mole of any substance has 6.02 x 10^23 atoms

So, 1 mole of SI = 6.02 x 10^23 atoms

5.0 moles = Z atoms

To get the value of Z, cross multiply:

(Z atoms x 1 mole) = (6.02 x 10^23 atoms x 5.0 moles)

Z atoms•1 mole = 30.1 x 10^23 atoms•moles

Divide both sides by 1 mole

Z atoms•1 mole / 1 mole = 30.1 x 10^23 atoms•moles / 1 mole

Z = 30.1 x 10^23 atoms

[Place Z in standard form

So, Z = 3.01 x 10^24 atoms]

Thus, there are 3.01 x 10^24 atoms in 5.0 moles in SI

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
