Final answer:
To calculate the amount of dextrose in 500 mL of D5W, we use the mass/mass percent concentration formula. The amount of dextrose in 500 mL of D5W is 25 grams.
Step-by-step explanation:
To calculate the amount of dextrose in 500 mL of D5W, we need to understand that D5W is an approximately 5% solution of dextrose in water. This means that 500 mL of D5W contains 5% dextrose by mass.
To calculate the mass of dextrose, we can use the mass/mass percent concentration formula. Mass percent = (mass of solute / mass of solution) × 100%. In this case, since we have 500 mL of solution, we can take 5% of 500 mL to find the mass of dextrose.
Answer: The amount of dextrose in 500 mL of D5W is 25 grams.
