Calculate the percent by volume of solute in the following solution: 20.0 mL of methyl alcohol
in enough water to give 475 mL of solution.


Sagot :

Given:

Solute: 20.0 mL of methyl alcohol

Solution: 475 mL of water

Required: % by volume of solute

Equation:

[tex]\% \: by \: volume \: = \frac{volume \: of \: solute}{volume \: of \: solution} \times 100[/tex]

Solution:

[tex]\% \: by \: volume \: = \frac{20 \: ml}{475 \: ml} \times 100[/tex]

(Cancel like units)

[tex]\% \: by \: volume \: = 0.0421 \: \times 100[/tex]

[tex]\% \: by \: volume \: = 4.21\%[/tex]

Therefore, the % by volume of solute will be 4.21%
