Question

8. An experiment requires a solution that is 80%

Answer 1

Answer:

$v_{solute}=160mL$

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the volume of methyl alcohol solute by using the definition of by-volume percentage:

$\%v=\frac{v_{solute}}{v_{solution}} *100\%$

Whereas we solve for the volume of the solute as shown below:

$v_{solute}=\frac{\%v*v_{solution}}{100\%} \\\\v_{solute}=\frac{80\%*200mL}{100\%}\\\\ v_{solute}=160mL$
