Determine the number of atom in 5.0 moles in SI
Alex

Answer: 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
