The density of ethanol is 0.789 g/mL. If you need 460.0 g of ethanol for an experiment, how many milliliters would you measure o

4vir4ik [10]

Answer:

The volume is 583.02 mL

Explanation:

Given that the density is:-

$\rho=0.789\ g/mL$

The mass, $m=460.0\ g$

The expression for the calculation of density is shown below as:-

$\rho=\frac{m}{V}$

Using the above expression to calculate the volume as:-

$V=\frac{m}{\rho}$

Applying the values to calculate the volume as:-

$V=\frac{460.0\ g}{0.789\ g/mL}=583.02\ mL$

<u>The volume is 583.02 mL.</u>
