Question 1:
Determine the volume/volume percent solution made by combining 25 mL of ethanol with enough water to produce 200 mL of the solution.
A. 12.8 %
B. 12.5 %
Feedback Given parameters are
Volume of solute is 25 mL
Volume of solution is 200 mL
Substitute the values in the given formula,
Volume percent = volume of solute /volume of solution x 100%
= 25 mL / 200 mL x 100%
= 12.5 %
C. 13.7 %
D. 15 %
