Explanation / Answer

1. Mole is a unit of measurement used to express amounts of a chemical substance. The concentration of a solution is mostly expressed by its molarity, which is the number of moles of the dissolved substance per litre of solution. One mole of glucose is equal to 180 grams. Since, 1 mole = 1000 milli moles, 26 mmol/L of glucose is equal to 4.68 grams/L of glucose (180* 26/ 1000). Thus, grams of glucose in orange pulp = 4.68 grams/L

2. Grams of glucose in orange pepsi = 1.08 grams/L

3. Diet pepsi = Neg

4. Grams of glucose in orange Apple juice = 2.52 grams/L

5. Grams of glucose in Lemonade Ice Tea = 3.78 grams/L

6. Grams of glucose in red rain = 2.88 grams/L

7. Grams of glucose in Lemonade = 2.70 grams/L
