Question

How many atoms are in 8.37 mol of Lithium?

Answer 1

he number of atoms of lithium is 5.039 x 10^24 atoms

Step-by-step explanation

Given that;

The number of moles of lithium is 8.37 mol

Follow the steps below to find the number of atoms of lithium

`\text{ mole = }\frac{\text{ number of atoms}}{\text{ Avogadro's number}}`

Recall, that the Avogadro's number is 6.02 x 10^23

`\begin{gathered} \text{ mole = }\frac{\text{ Number of atoms}}{\text{ Avogadro's number}} \\ \\ \text{ 8.37 = }\frac{\text{ number of atoms}}{\text{ 6.02 }*\text{ 10}^(23)} \\ \text{ cross multiply} \\ \text{ Number of atoms = 8.37 }*\text{ 6.02 }*\text{ 10}^(23) \\ \text{ Number of atoms= 50.39 }*\text{ 10}^(23) \\ \text{ Number of atoms = 5.039 }*\text{ 10}^(24)\text{ atoms} \end{gathered}`

Therefore, the number of atoms of lithium is 5.039 x 10^24 atoms
