= A 0.5099 g mixture of KCN (MW 65.116 g/mol) and NaCN (MW = 49.005 g/mol) was dissolved in water. AgNO, was added to the solution, precipitating all of the CN in solution as AgCN (MW : 133.886 g/mol). The dried precipitate weighed 1.184 g. Calculate the weight percent of KCN and NaCN in the original sample. KCN wt% = NaCN wt% = = % %
A 25mL volumetric pipet is used to deliver a sample of the stock solution marked “0.6000M X2SO4” into a 100mL volumetric flask. Distilled water is added to the flask until it is about 3/4thfull, the solution is mixed well, then more water is added to fill it up to the calibration mark, then it is mixed again. Calculate the concentration of X+ion in the dilute solution made above.

A pipet is used to transfer 5.00 mL of a 1.25 M stock solution in flask "S" to a 25.00-mL volumetric flask "B," which is then diluted with DI H,0 to the calibration mark. The solution is thoroughly mixed. Next, 2.00 mL of the solution in volumetric flask "A" is transferred by pipet to a 50.00-mL volumetric flask "B" and then diluted with DI H,0 to the calibration mark. Calculate the molarity of the solution in vol- umetric flask “B."
VIII. A primary standard of HCI is sodium carbonate, Na2CO3. A measured mass of solid Na2CO3, mNa2CO3' in grams, is dissolved in water and then titrated with HCI solution using methyl 2 NaCl + CO2 + H2O. orange indicator. The reaction is: Na2CO3 + 2 HCI- Complete the following formulas using the context described above: MHCI × VHCI in mL at the methyl orange endpoint = mNa2CO3 × ( )= mol of Na2CO3 mol of Na2CO3 X (— ( - - )= mol of HCl

During Lab 4, you are titrating a sample of new orange juice to determine its ascorbic acid (aka vitamin C) content. You have previously determined an experimental conversion factor of 0.26 mg ascorbic acid/mL dye using an ascorbic acid standard. After measuring out 5.16 mL of your orange juice sample and ~10 mL of 3% metaphosphoric acid to a graduated cylinder, you dilute the solution to 50.33 mL with DI water. You finally dispense 10.87 mL of the diluted solution into an Erlenmeyer flask, add 4 drops of HCl, and use 6.48 mL of dye to reach the equilibration point. How much ascorbic acid (mg) is in your concentrated orange juice sample? The molecular weight of ascorbic acid is 176.12 g/mol.
