Identify the given quantity: 3.01 \(\times\) 10^{22} atoms of magnesium (Mg).
Recall that 1 mole of any substance contains Avogadro's number of particles, which is approximately 6.022 \(\times\) 10^{23} atoms/mol.
Set up the conversion from atoms to moles using the relationship: \(\text{moles} = \frac{\text{number of atoms}}{\text{Avogadro's number}}\).
Substitute the given values into the formula: \(\text{moles} = \frac{3.01 \times 10^{22}}{6.022 \times 10^{23}}\).
Perform the division to find the number of moles of magnesium atoms present.
