Q1. Tabulate the main group findings (you can only have one table and this table must fit a single page – think about how the table should be presented and what additional information must come with the table; you do not need to present data on your blanks and standards).
Q2. What were the four main findings of this practice as a whole?
Q3. How do the measured amounts of vitamin C on the orange juice samples open only at the start of the practical compare to the values found on the food tables and the food labels? Are they different? Why? (note: you need to address possible limitations regarding the data present on the Food Composition Tables and also experimental procedure).
