##### 1 Answer

The given sample of vinegar is 5.1% acetic acid by mass.

This means

It is assumed tha density of vinegar is

So we can say

So the strength of vinegar solution is

Now molar mass of

So strength of the acetic acid solution

Volume of acetic acid solution

Let this solution is nutralised by

The balanced equation of nutralisation reaction is

This equation reveals that the stochiometric ratio of reactants is

So this follows the relation
