Remembering the formula of density, we can clear the volume and replace the given data in the new formula:
[tex]\begin{gathered} \text{density}=\frac{mass}{volume}, \\ \text{volume}=\frac{mass}{density}. \end{gathered}[/tex]Our data is: for mass is 17.7 grams (g) and for density is 0.727 g/mL:
[tex]\text{volume}=\frac{17.7\text{ g}}{0.727\text{ }\frac{g}{mL}}=24.347mL=24.3mL.[/tex]The volume of the ether is 24.3 mL of 17.7g and 0.727 g/mL.
