Benzene sulfonic acid, C6H5SO3H, is a strong acid and will neutralise sodium hydroxide solution (a 1:1 molar ratio). Benzene sulfonic acid crystals (y grams) were weighed into a titration flask and titrated against sodium hydroxide solution (1.0 M) and needed a volume of 26.2 cm3. What was the mass, y grams, of benzene sulfonic acid used (use C = 12, H = 1, S = 32, O = 16 amu)?

mol NaOH = M x L = ?
mols acid = mols NaOH
mols acid = grams/molar mass. You know molar mass and mols, solve for grams.
