How many calories are provided in 1.5 L of D25W?

To determine how many calories are provided in 1.5 L of D25W (25% dextrose in water), it’s important to understand the composition of the solution. D25W contains 25 grams of dextrose per 100 mL.

First, calculate the total grams of dextrose in 1.5 liters:

1.5 L is equivalent to 1500 mL. Since there are 25 grams of dextrose in 100 mL, we can find out how many grams are in 1500 mL using the following proportion:

(1500 mL / 100 mL) * 25 grams = 375 grams of dextrose.

Next, to convert grams of dextrose to calories, we use the fact that each gram of carbohydrate provides approximately 4 calories. Therefore, the total calories from the dextrose in 375 grams is calculated by multiplying the grams by the caloric value:

375 grams * 4 calories/gram = 1500 calories.

However, the question asks about how many calories are provided in a specific volume of D25W, which is important to reassess after calculating the initial dextrose portion. The answer should correspond to
