C (vinegar) = 60g/mol
Mole
The mole is the unit of measurement in the International System of Units (SI) for amount of substance. It is defined as the amount of a chemical substance that contains as many elementary entities, e.g., atoms, molecules, ions, electrons, or photons, as there are atoms in 12 grams of carbon-12 (C), the isotope of carbon with relative atomic mass 12 by definition.
Is acetic acid and vinegar the same thing?
Vinegar is 7-8% solution by volume Acetic Acid, while Acetic acid is pure Acetic acid itself. The IUPAC name of Acetic Acid is Ethanoic Acid. 100% pure Acetic acid is glacial Acetic acid. It solidifies just below normal room temperature. 5–8% Acetic acid in Water is called Vinegar. Vinegar is 5% acetic acid.
Is acetic acid stronger than citric acid?
Acetic acid, also named named ethanoic acid, is an organic acid with the chemical formula CH3COOH while citric acid, also weak organic acid has the chemical formula C6H8O7. Both of these are relatively weak acids, but citric acid is slightly stronger than acetic acid.
Does vinegar interact with acetic acid?
Yes, vinegar is a mixture of acetic acid and water. If you dissolve salt in vinegar, it is a three part mixture of water, acetic acid and sodium chloride. Since none of these components will react with one another, they will remain a mixture after they are combined. 525 views.
Is acetic acid the most volatile liquid?
Acetic acid is a colourless liquid; with a strong vinegar-like odour. It is flammable, and at temperatures warmer than 39°C, explosive vapour/air mixtures may be formed. Acetic acid is considered a volatile organic compound by the National Pollutant Inventory.

How do you find the molar concentration of acetic acid in a vinegar sample?
You will want to multiply the moles calculated by 4 to get moles of acetic acid in the 100mL of 10% solution. Then by dividing these moles by the volume of original acid that was diluted into 100 mL (because the moles of acetic acid all came from the 10 mL of vinegar), the molarity of the acetic acid can be found.

What is titration in chemistry?
Titration is a method used in order to ascertain the amount of a constituent in a solution by measuring the volume of a known concentration of a reagent required to complete a reaction with it , typically using a burette. The equivalence point of a titration occurs when chemically equivalent amounts of acid and base are present.
What is the equivalence point of a titration?
The equivalence point of a titration occurs when chemically equivalent amounts of acid and base are present. In this experiment, the equivalence point occurs when the moles of acid in the solution equals the moles of base added in the titration. A rapid change in pH with the small addition of acid or base is the indicator of acid-base equivalency.
