How many moles of neon(Ne, 20.18 g/mol) are in 68.4grams of neon?[?] moles

To calculate the number of grams we use the atomic weight of Neon(. This value can be found in the periodic table of elements and we apply the following relationship:

$\begin{gathered} \text{Moles of Ne = Given g Ne}*\frac{1molNe}{AtomicMass\text{, g Ne}} \\ \text{Moles of Ne = }68.4\text{ g Ne}*(1molNe)/(20.18gNe) \\ \text{Moles of Ne = }3.4\text{mol Ne} \end{gathered}$

In 68.4 grams of Neon, there are 3.4 Mol Neon
