Answer :
Answer:
Explanations:
To calculate the number of moles of ethane (C2H6), we will use the formula;
[tex]\text{Number of moles=}\frac{\text{Number of molecules}}{Avogadros\text{ number}}[/tex]Given the following parameters:
[tex]\begin{gathered} \text{Molecules of C}_2H_6=4.3\times10^{25} \\ \text{Avogadros number = 6.02}\times10^{23} \end{gathered}[/tex]Substitute the given parameters into the formula:
