Considering the definition of percent by volume concentration, the correct answer is option D: the percent by volume concentration of the solution is 1.50%
Percent by volume concentration is a measure of concentration that indicates the volume of solute per 100 volume units of the solution. This value is calculated by dividing the volume of the solute by the total volume of the solution, and multiplying by 100 to express it as a percentage:
[tex]percent by volume concentration=\frac{volume of solute}{total volume of the solution}x100[/tex]
In this case, you know:
Replacing in the definition of percent by volume concentration:
[tex]percent by volume concentration=\frac{3 mL}{200 mL}x100[/tex]
Solving:
percent by volume concentration=0.015×100
percent by volume concentration=1.50
Finally, the correct answer is option D: the percent by volume concentration of the solution is 1.50%
