Essential nutrients
These are the organic compounds present in the food that provide nourishment essential for the development and growth of our body. Nutrients not only provide us with the required energy to carry out various biological processes but are also the building blocks for repair and growth in our bodies.
Vitamins
The vitamins are organic molecules required in low concentration for the proper functioning of the body. They cannot be generated in the organism and are taken into the body through the diet. The lack of proper vitamins results in diverse deficiency disorders. They are thus called essential nutrients. The important vitamins are vitamin A, vitamin B complex, vitamin C, vitamin D, vitamin K, and vitamin E.
Question
![### Preparing a 20% Glucose Solution
Your research advisor asks you to prepare 1 liter (L) of a 20% glucose solution. How much glucose (in grams, g) do you need to weigh?
- O 20 g
- O 200 g
- O 0.2 g
- O It is not possible to answer this question without knowing the molecular weight of glucose.
In this question, you are required to determine the amount of glucose needed to prepare a solution with a specific concentration. The correct option will be one that aligns with the calculation for a 20% solution. Here's the approach to solve it:
### Solution Explanation:
A 20% glucose solution means there are 20 grams of glucose per 100 milliliters of solution. Therefore, for 1 liter (1000 milliliters) of solution, you would need:
\[ \text{Total Glucose} = \frac{20 \, \text{g}}{100 \, \text{mL}} \times 1000 \, \text{mL} = 200 \, \text{g} \]
Thus, the correct answer is:
- O 200 g](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb9dff0bf-37a6-45cf-823f-0c28f5d6c073%2Fc94bf2c3-2fbc-4a46-94b3-c16ff61eeff4%2Fudk6ota.jpeg&w=3840&q=75)
