Solid ammonium chromate is slowly added to 175 mL of a 0.397 M calcium nitrite solution until the concentration of chromate ion is 0.0543 M. The mass of calcium ion remaining in solution is grams.

In the laboratory, a student dilutes 22.3 of 6.05 M perchloric acid solution to a total volume of 300.0 mL. What is the concentration of the diluted solution?

16.792 g of Ba(OH)2 (171.342 g.mol') is weighed out and carefully dissolved to make a 500.00cm solution. A 25.00 cm of this solution is pipette then transfer into a 100.00 mL volumetric flask, filling up to the mark with water. A 40.00 mL sample of this diluted solution is then reacted with a 0.753 M solution of HNO3. Ba(OH)2(aq) + 2HNO3(aq) → Ba(N03)2(aq) + 2H2O(1) The concentration of Ba(OH)2 in the 100.00 cm3 volumetric flask is: O 1.96 x 103 M O 5.21 x 10-3 m O 4.90 x 10 2M O 1.96 x 101 M O 3.92 x 103 M O None of the above

Aqueous silver (I) nitrate reacts with aqueous sodium chloride to produce solid silver (I) chloride and aqueous sodium nitrate. A 25.00 mL solution of silver (I) nitrate is mixed with a 25.00 mL solution of sodium chloride. The resulting aqueous sodium nitrate has a concentration of 0.5000 M.
