Three different solutions were prepared in the laboratory. One was prepared by dissolving 82 g of KCI in enough water to make 300 milliliters of solution. Another was prepared by diluting 150mL of 8.0 molar of KCI to 500 mL. The third solution was prepared by aliquoting 5 mL each from the first two solutions and diluting it to 50mL. If 25 mL aliquot from the first solution, 20 ml aliquot from the second solution and 30 mL aliquot from the third solution were mixed. What is the concentration of the final solution?
How many milliliters of a stock solution of 7.00 MM HNO3HNO3 would you have to use to prepare 0.170 LL of 0.550 MM HNO3HNO3? V= mL If you dilute 16.0 mLmL of the stock solution to a final volume of 0.350 LL , what will be the concentration of the diluted solution? M= M
When a Vitamin C (ascorbic acid; MM = 176.12 g mol-1) tablet is crushed, dissolved and titrated with 0.0340 M KIO3(aq) to a purple/blue endpoint (given by a starch indicator), the volume of KIO3 used is 29.80 mL. If 60 mg of ascorbic acid is the recommended dietary allowance (i.e., 100% of the RDA), then what is the % RDA for the Vitamin C in the tablet? KIO3(aq) + 5 KI + 6 H+ → 3 I2(aq) + 3 H2O I2 (aq) + ascorbic acid → 2 I- + dehydroascorbic acid

What volume (in mL) of a soft drink that is 10.5% sucrose (C12H22O11) by mass contains 78.5 g of sucrose (d=1.04g/mL)?
We did a titration experiment on the percent acetic acid in a vinegar brand. For the titrant, we used 1M NaOH while the solution of the analyte contains 5mL of the vinegar solution with 20 mL of distilled water and 5 drops of phenolphthalein. After titration, 3.7mL of NaOH was used before the solution in the flask turned pale pink. My questions are: What is the mass percent of acetic acid in the vinegar? What would be the effect on the percent acetic acid if 25 mL of vinegar had been used instead of 5 mL? kindly explain.
