Question

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

Answer 1

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
