Question

Calculate the number of grams of dextrose in 500 ml of a 5% dextrose solution.

A) Less than 25g
B) 25g
C) Between 25g and 30g
D) More than 30g

Answer 1

The amount of dextrose in 500 ml of a 5% dextrose solution is 25 grams.

Step-by-step explanation:

To calculate the number of grams of dextrose in a 500 ml of a 5% dextrose solution, we use the percentage by mass definition. A 5% dextrose solution means that there are 5 grams of dextrose for every 100 milliliters of solution. Since the question asks for the amount in 500 ml, we calculate this by scaling up the concentration proportionally:

5 grams/100 ml × 500 ml = 25 grams

Therefore, the amount of dextrose in 500 ml of a 5% dextrose solution is 25 grams.
