Which is more concentrated vinegar ( 5%. W/ acetic acid or 1 M acetic acid.

1 M acetic acid is more concentrated than 5% vinegar with acetic acid.

This is because 5% vinegar means there is 5% acetic acid in the solution, whereas 1 M acetic acid means there is 1 mole of acetic acid in 1 liter of the solution, which is a much higher concentration.

The concentration of vinegar is typically expressed as a percentage of acetic acid. Therefore, comparing a 5% vinegar solution with 1 M (Molar) acetic acid is not straightforward, as they represent different units of concentration.

A 5% vinegar solution means that it contains 5 grams of acetic acid per 100 milliliters of solution.

On the other hand, 1 M acetic acid refers to a solution where the concentration of acetic acid is 1 mole per liter. This means that in 1 liter of the solution, there would be 1 mole (around 60 grams) of acetic acid.

To determine which solution is more concentrated, you would need to convert one unit of concentration to the other.

If you know the density of the vinegar, you can convert the 5% vinegar solution to grams of acetic acid per liter. Then you can compare it with the 1 M acetic acid solution.

Without the density of the vinegar, it is not possible to directly compare the concentration of a 5% vinegar solution and 1 M acetic acid.
