Answer:
1. 64.29%
2. 16.67%
Explanation:
1. Given: mass of solute = 45ml ethyl
mass of solution = 70 ml
Reqrd: Percent by Volume of the solute
Solution:
[tex]\% = \frac{mass \: ofsolute}{mass \: of \: solution} \times 100 \\ \% = \frac{45ml}{70ml} \times 100 \\ \% = 0.6429 \times 100 \\ \% = 64.29[/tex]
ANS. The percent by volume of the ethyl is 64.29%.
2.Given: mass of solute = 12 g
mass of solution = 72 g
Reqrd: Percent by Volume of the solute
Solution:
[tex]\% = \frac{12g}{72g} \times 100 \\ \% = 0.1667 \times 100 \\ \% = 16.67[/tex]
ANS. The percent by volume of sugar is 16.67%.
