A titration of sulfates in a 5.00 mL sample of drinking water with 10.0 mM (millimolar) of barium acetate as the titrant is carried out. A microflow pump was used instead of a buret, set at a flow rate of 0.122 mL/min. The equilibrium point is reached at 120 seconds. After 200 seconds has passed, what is the concentration of sulfates in the drinking water sample.
