Question

Calculate the number of moles equal to 4.3 x 10^25 molecules of C2H6

Answer 1

Explanations:

To calculate the number of moles of ethane (C2H6), we will use the formula;

`\text{Number of moles=}\frac{\text{Number of molecules}}{Avogadros\text{ number}}`

Given the following parameters:

`\begin{gathered} \text{Molecules of C}_2H_6=4.3*10^(25) \\ \text{Avogadros number = 6.02}*10^(23) \end{gathered}`

Substitute the given parameters into the formula:
