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:
[tex]\begin{gathered} \text{Moles of Ne = Given g Ne}\times\frac{1molNe}{AtomicMass\text{, g Ne}} \\ \text{Moles of Ne = }68.4\text{ g Ne}\times\frac{1molNe}{20.18gNe} \\ \text{Moles of Ne = }3.4\text{mol Ne} \end{gathered}[/tex]
In 68.4 grams of Neon, there are 3.4 Mol Neon
