A chemical process requires a certain amount of acetic acid to be added to a reaction mixture. The reaction requires a stoichiometric ratio of 2 moles of acetic acid to 1 mole of the other reactant. The reaction mixture has a total volume of 1000 L and the desired concentration of acetic acid is 0.5 M. Acetic acid is available in the form of a 98% pure solution with a density of 1.05 g/mL. What mass of the acetic acid solution needs to be added to the reaction mixture to achieve the desired concentration of acetic acid? Assume that the density and percentage purity of the acetic acid solution remain constant regardless of the amount of solution added.
