If the % acetic acid listed on a vinegar bottle is 4%, what is the implied uncertainty of the acetic acid concentration
Tom [10]

Answer:

This question appears incomplete

Explanation:

This question appears incomplete because the data provided only makes it possible to calculate the certainty of the acetic acid content per total volume of the vinegar. Thus, the 4% means for every 100 mL of the vinegar, there is 4 mL of acetic acid present. To calculate the volume of acetic acid in any other volume of vinegar, the formula will be

volume of acetic acid = 4/100 × total volume of vinegar
