A student mixed 100.00 mL of Ba(OH):(aq) (unknown molarity) with 500.00 mL of 0.0200 M NaOH(aq) in a conical flask to make up Solution A. He then transferred 25.00 mL of Solution A to a 250.00-mL volumetric flask and added distilled water up to the calibration mark to make up Solution B. The concentration of the hydroxide ions in Solution B is 2.00 x 10mol/L. Calculate the molarity of the original solution of Ba(OH)2.
