Sulfuric acid is a stronger base, meaning it more completely dissociates. Acetic acid does not completely dissociate, and therefore does not change the concentration of hydrogen ions in solution to the extent that sulfuric acid does. Since pH = -log[Hydrogen ions], sulfuric acid will have a lower pH.
Sulfuric acid is diprotic. The first dissociation of sulfuric acid is the "strong" one, and the second is weak. So, compared to hydrochloric acid, which is monoprotic, sulfuric acid will contribute more protons to the solution, and thus have a lower pH.

to determine the concentration of the unknown solution and to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH.
The molar mass of acetic acid is 60,05 g.
These are two different compounds.
For acetic acid the molar and normal concentrations are identical.The value is 60,05 g/L.

to determine the concentration of the unknown solution and to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH.
Not necessarily or even usually. The term "one molar" refers to the concentration of the acid added and does not have anything to do with the concentration of ferrous ions.

To prepare a 0.1 N glacial acetic acid solution, calculate the required mass by multiplying 0.1 moles by the molar mass of glacial acetic acid (60.05 g/mol). Weigh out the calculated mass and add it to a clean container. Dissolve the glacial acetic acid completely by stirring it with distilled water. Transfer the solution to a 1-liter volumetric flask and dilute it to the 1-liter mark with distilled water. Mix thoroughly, label, and store the solution properly, taking necessary safety precautions when handling glacial acetic acid.
10 percent acetic acid indicates there is .1 liters of acetic acid, which is equal to 1.75 moles, or 105 grams per liter. To make this solution, add 7 liters of the 2M solution to 1 liter of water, or 7/8 solution to 1/8 water.
