The formula of citric acid is C5H4O5, its gram molecular mass is 192.14, and the gram Atomic Mass of oxygen is 15.9994. Therefore, the fraction by mass of oxygen in citric acid is 5(15.9994)/192.14 or 0.4162 and the mass of oxygen in 20.2 units of citric acid is 0.4162(20.2) or 8.41 of the same units, to the justified number of significant digits.
There are approximately 192 grams of citric acid in one cup.
There are approximately 28 grams in one ounce of citric acid.
Lemon juice contains approximately 1.44 grams per ounce of citric acid.

The concentration of citric acid in juice can vary, but on average it is around 0.5-1% of the total volume. Therefore, 10 liters of juice would contain approximately 50-100 grams of citric acid.
There are approximately 393.92 grams of citric acid powder in a cup. Calculations are as follows: 236.588236 cm3 / 1 US cup X 1.665 grams of citric acid / 1 cm3 of citric acid = 393.9194129 grams of citric acid / 1 US cup Conversion from US cups to cubic centimeters obtained from Google calculator http://www.google.com/search?sourceid=chrome&ie=UTF-8&q=1+cup+to+cubic+centimeters
To determine the purity of citric acid by titration, you would need to titrate a known concentration of a base (such as NaOH) with a solution of citric acid. The amount of base required to neutralize the citric acid can be used to calculate the purity of the citric acid sample. The purity can be calculated by comparing the experimental results to the theoretical stoichiometry of the reaction.
Lemon juice contains approximately 1.44 grams per ounce of citric acid.
The percentage of hydrogen in citric acid is 4,198 68 %.
