Suppose you titrate a 25.00 mL sample of vinegar with 17.62 mL of a standardized .1045 N solution of NaOH.
a.) What is the molarity of acetic acid in the vinegar?
b.) What is the mass of acetic acid contained in 1.000L of vinegar?

(17.62 mL) x (0.1045 N) / (25.00 mL) = 0.07365 N = 0.07365 M acetic acid

Supposing it is the same vinegar in parts a. and b.:
(1.000 L) x (0.07365 mol/L) x (60.0522 g CH3CO2H/mol) = 4.423 g acetic acid
