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%
