Citric acid H3C6H5O7, occurs in plants. Lemons contain 5% to 8% citric acid by mass. The acid is added to beverages and candy. An aqueous solution is 0.688m citric acid. The density is 1.049 g/ml. What is the molar concentration?

m = mols/kg solvent
1 kg solvent has a mass of 1,000 g and a volume of v = m/d = 1000/1.049 = 953.3 mL or 0.9533 liters. Then Molarity = mols/L. You have 0.688 mols and you have 0.9533 L so the molarity = ??
check my thinking.
