Question
How many grams of glucose are there in a 500. mL isotonic solution of 5.00 % dextrose (glucose)?
Group of answer choices
- 25.0 g
- 5.00 g
- 100 g
- 0.01 g
Solution
First, we need to understand that a 5.00% dextrose solution means that there are 5.00 grams of glucose in every 100 mL of solution.
Next, we need to find out how many grams of glucose are in 500 mL of solution. Since the percentage is based on a 100 mL solution, we can set up a proportion to find the answer:
5.00 g/100 mL = x g/500 mL
Cross-multiplying gives us:
5.00 g * 500 mL = 100 mL * x g
Solving for x gives us:
x = (5.00 g * 500 mL) / 100 mL = 25.0 g
So, there are 25.0 grams of glucose in a 500 mL isotonic solution of 5.00% dextrose.
