Avogadro's Number = 6.023 10^23 substitutue 1 for any solids/liquids, and P, (assuming constant volume in a closed system and no accumulation of intermediates or side products). You find that the solution has an osmotic pressure of 539 mm Hg at 25 C. What is the composition of the mixture? The equivalence point of the titration occurred at 23.82 mL. b. Please resubmit the question once again, A: According to guidelines, we have to attempt first part. a KCl + b H 2 C 4 H 4 O 6 = c KHC 4 H 4 O 6 + d HCl. Calculate the molarity. What is the minimum mass of solid KI and the minimum volume of 3.00 M HQ required to convert all of the IO3 ions to I ions? What does this reveal about the ability of the acids anion to attract protons? We have to determine if half A: Due to technical error ,unable to provide you the solution. NAME A: If the beverage is 0.671 M in tartaric acid, what is the molal concentration? . Assuming the density of the vinegar to be 1.0 g / mL, what was the percent (by mass) of acetic acid in. PART B: Second, what is its K b when it acts as a base? A solution containing an unknown concentration of the Write a balanced net ionic equation for the neutralizationreaction, and calculate the molarity of the tartaricacid solution.
