Question

A 750 ml bottle of solution is labeled 5% dextrose and 0.45% sodium chloride. How many grams of dextrose are in the bottle of solution?

A) 37.5 g

B) 75 g

C) 112.5 g

D) 150 g

Answer 1

To calculate the grams of dextrose in the bottle, we use the percent concentration of 5% dextrose, which gives us 37.5 grams in a 750 ml bottle, corresponding to option A) 37.5 g.

Step-by-step explanation:

The student is asking how many grams of dextrose are in a 750 ml bottle of solution that is labeled as 5% dextrose. To find out the quantity of dextrose in grams, we can use the percent concentration of the solution. Since 5% means that there are 5 grams of dextrose per 100 milliliters of solution, we can calculate the total amount of dextrose in a 750 ml solution by creating a proportion:

5 grams/100 ml = x grams/750 ml

Solving for x gives us:

x = (5 grams/100 ml) × 750 ml

x = 37.5 grams

Therefore, there are 37.5 grams of dextrose in a 750 ml bottle of solution, which matches option A) 37.5 g.
