Final Answer:
To determine the volume of rubbing alcohol present in a 200-mL sample of the solution, you can use the following calculation: Volume of rubbing alcohol = Percentage of alcohol × Total volume of solution. Therefore, in a 200-mL sample of the 60% (v/v) rubbing alcohol solution, there are 120 mL of pure rubbing alcohol.
Step-by-step explanation:
A 60% (v/v) solution of rubbing alcohol indicates that 60% of the volume of the solution is composed of pure rubbing alcohol (isopropyl alcohol), while the remaining 40% is likely water or another solvent.
To determine the volume of rubbing alcohol present in a 200-mL sample of the solution, you can use the following calculation:
Volume of rubbing alcohol = Percentage of alcohol × Total volume of solution
Substitute the given values:
Volume of rubbing alcohol =0.60 × 200 mL
Volume of rubbing alcohol = 120 mL
Therefore, in a 200-mL sample of the 60% (v/v) rubbing alcohol solution, there are 120 mL of pure rubbing alcohol.
