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

Answer 1

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.
