When a Vitamin C (ascorbic acid; MM = 176.12 g mol-1) tablet is crushed, dissolved and titrated with 0.0377 M KIO3(aq) to a purple/blue endpoint (given by a starch indicator), the volume of KIO3 used is 40.01 mL. How many mg of Vitamin C were in the tablet? KIO3(aq) + 5 KI + 6 H+ → 3 I2(aq) + 3 H2O I2 (aq) + ascorbic acid → 2 I- + dehydroascorbic acid
Please help me with this one Sugar is the solute and water is the solvent. The drink mix will be considered negligible and is added simply for the visualization of dilution results. Calculate the concentration of sugar in this solution using the volume percent equation. Refer to the background for sample calculations. For the purpose of this exercise, it can be assumed that the weight of the drink mix is 0.00 g. The volume of the solution is 3 and 1/3 cups. Convert to metric units, then calculate and record the volume percent in Data Table 1 (Note that 1 cup = 236 mL). Volume % = Volume of Solute/ Volume of Solution × 100%

A chemistry student is given 1.00 L of a clear aqueous solution at 17 degrees Celsius. He is told an unknown amount of a certain compound X is dissolved in the solution. The student allows the solution to cool to 17 degrees Celsius. The solution remains clear. He then evaporates all of the water under vacuum. A precipitate remains. The student washes, dries and weighs the precipitate. It weighs 0.12 kg. Using only the information above, can you calculate the solubility of X in water at 17° C? If you said yes, calculate it and be sure your answer has a unit symbol and 2 significant digits.
