Commercial vinegar usually has a concentration of 5%, per volume.

a) Calculate the [H3O+] , if the density of acetic acid is 1.051 g/mL.

b) Calculate the pH.

• Chemistry -

5% w/v means 5 g acetic acid/100 mL soln.
You can convert to M by
5g/molar mass = mols.
mols/L soln = M
You need a K to calculate H^+.
