As food manufacturers add vinegar to food preparations to make them tart, rather than pure acetic acid, you should estimate the percentage of total vinegar in the same. This calculation assumes that vinegar is 5% acetic acid by weight.
Volume, mL of vinegar: 5ml
Molarity of CH3COOH: 0.125M
% by weight CH3COOH: 0.871%
Density of vinegar: 1.008 g/ml
