The concentration of SO42β ions in a 60.0 mL sample of seawater is determined by adding a solution of BaCl2 and precipitating the SO42β as BaSO4. After the precipitate is filtered from the solution, it is dried and weighed. If the mass of BaSO4 recovered is 0.448 g, what is the sulfate concentration of the seawater sample? Express your answer in mmol/L.
