5.00 mL of stock solution is diluted to 25.00 mL, producing solution ALPHA. 10.00 mL of solution ALPHA is diluted to 25.00 mL, resulting in solution BETA. 10.00 mlL of solution BETA is then diluted to 25.00 mL, producing solution GAMMA.

When 200.0 mL of a solution containing 0.4522 g of AgNO3 is mixed with 100.0 mL of a solution containing 0.1668 g of K2CRO4, a bright red Ag2CrO4 precipitates. a. Identify the limiting reagent. b. Calculate the mass of the precipitate. c. Calculate the mass of the unreacted AgNO3 or K2CrO4 that remains in solution. 5. A series of sulfate samples is to be analyzed by precipitation as BaSO4. To obtain four significant digits at least 0.1000 g BaSO4 should be obtained. a. If the sample contains at least 10% sulfate by weight, what is the minimum sample mass that can be used? b. If this amount is used and the sample turns out to actually contain 42% sulfate, what mass of precipitate would be obtained?
