Question

If the density of an ether was 0.727g/mL and the mass 17.7 grams, what is the volume?Report the answer in (mL) to three significant figures and also include the correct unit

Answer 1

Remembering the formula of density, we can clear the volume and replace the given data in the new formula:

`\begin{gathered} \text{density}=(mass)/(volume), \\ \text{volume}=(mass)/(density). \end{gathered}`

Our data is: for mass is 17.7 grams (g) and for density is 0.727 g/mL:

`\text{volume}=\frac{17.7\text{ g}}{0.727\text{ }(g)/(mL)}=24.347mL=24.3mL.`

The volume of the ether is 24.3 mL of 17.7g and 0.727 g/mL.
