The volume of acetic acid in a sample of 500mL of vinegar is determined to be 1mL. What is the v/v percentage of the vinegar?
What's the density of acetic acid?
mass = 1 mL x density (in g/mL)
That's the mass in 500 mL? 1/5 of that is the mass in 100 mL.

To find the v/v percentage of the vinegar, you need to calculate the ratio of the volume of acetic acid to the total volume of the vinegar sample.
1. Start by converting the given volumes to the same unit. In this case, both volumes are already in milliliters (mL), so no conversion is needed.
2. Calculate the v/v percentage using the formula:
v/v percentage = (volume of acetic acid / total volume of vinegar) x 100
In this case, the volume of acetic acid is 1 mL, and the total volume of the vinegar sample is 500 mL:
v/v percentage = (1 mL / 500 mL) x 100
Simplifying the expression gives:
v/v percentage = 0.002 x 100
Therefore, the v/v percentage of the vinegar is 0.2%.
Note: The v/v percentage represents the volume of a particular component (in this case, acetic acid) per 100 mL of the solution.
