When making some vinegar based pickles, some 4.95 % by volume vinegar was diluted according to a recipe. What is the concentration in molarity (M, mol/L) of the vinegar if you added 2.325 L water to 0.400 L of the 4.95 % vinegar? Potentially useful information: density of the vinegar is 0.960 g/mL and the molar mass of vinegar is 60.052 g/mol.

Vinegar is sold as % acidity which means a weight/volume or w/v% calculation. The density of acetic acid is 1.05 g/ml and water is (effectively) 1.0 g/ml. Recollect (from CHMY121) the %w/v refers to a solution with a certain mass of additive made up to 100 mL with the addition of (in this case) water; or % m/v= (grams of solute / 100 mL solution) ×100 The molar mass of Acetic Acid is 60.052 g/mol. What is the molarity of...
