1. All answers to be entered via short answer are in the numerical format and presented up to the 3rd decimal place. Add trailing zeros if necessary, to complete your answer. NO NEED TO INCLUDE THE UNIT. For uniformity of answers, please be guided by the following examples: If your answer is 5.627594, enter 5.628 If your answer is 3.129934, enter 3.130 If your answer is 8.38, enter 8.380 If your answer is 1.2, enter 1.200 If your answer is 25, enter 25.000 If your answer is less than the value of 1, always place a zero before the decimal point (example: 0.5, enter 0.500) 2. In cases for answers in the exponential format, please be guided by the following examples and format: Do not convert your answer to decimal format If your answer from the calculator is 1.23454566 x 10E-4, enter 1.235x10^-4 (no spaces in between) If your answer from the calculator is 7.379566 x 10E-5, enter 7.38x10^-5 (no spaces in between) 3. For the atomic weights, it should be rounded to the nearest whole number. Example: Hydrogen: 1.00784 = 1.000 Questions: 1. Based from the given problem, What is the molecular weight  of the tartaric acid (C4H6O6)? 2. Based from the given problem, What is the meq of the tartaric acid (C4H6O6)? 3. Based from the given problem, What is the percentage purity of the tartaric acid (C4H6O6)?
Part 2: Assay of tartaric acid (Jenkin's Quantitative Pharmaceutical Chemistry by Knevel, pp.108)
Place about 2 g of tartaric acid previously dried and accurately weighed in a conical flask. Dissolve it in 40
ml of water, add a few drops of phenolphthalein TS, and titrate with 1 N sodium hydroxide! Each ml of 1 N
sodium hydroxide is equivalent to 75 mg of tartaric acid.
*Note: Volume of sodium hydroxide was observed at 26.5 ml
USP Requirement: Not less than 99.7 and not more than 100.5%)
