Vinegar is 5% acetic acid. Density of pickle juice is 1.05g/ml. Vinegar is 0.25 M acetic acid

Vinegar is 5% acetic acid.

This tells you that for each 1000 g of vinegar, you have 50 g of acetic acid

Vinegar is 0.25 M acetic acid

This tells you that for each 1000 mL of vinegar, you have 0.25 mol of acetic acid.

Those two are already contradictory since the first says that there are 5/6 mol of acetic acid in the vinegar and the second says that there are 0.25 mol of acetic acid in the vinegar...
