Question

Calculate the number of grams of dextrose in 500 mL of D5W. The concentration is 5 grams/100 mL.

A) 20 grams
B) 25 grams
C) 30 grams
D) 35 grams

Answer 1

To calculate the grams of dextrose in 500 mL of D5W with a concentration of 5 grams/100 mL, you multiply 5 grams by the volume proportion of 5, which equals to 25 grams. The correct answer is (B).

Step-by-step explanation:

To calculate the number of grams of dextrose in 500 mL of D5W when the concentration is 5 grams/100 mL, you use the following calculation:

• First calculate the total volume proportion: 500 mL is 5 times the 100 mL reference volume.
• Then multiply the 5 grams per 100 mL by the volume proportion (5) to get the total grams in 500 mL.

This gives us: 5 grams/100 mL × 5 = 25 grams of dextrose.

Therefore, the correct answer is B) 25 grams.
