How many calories are contained in 1.5L of a 25% dextrose solution?

To determine the number of calories in 1.5L of a 25% dextrose solution, you first need to know the concentration of dextrose in the solution. A 25% dextrose solution means that there are 25 grams of dextrose in every 100 mL of the solution.

1. Calculate the total amount of dextrose in 1.5L (or 1500 mL):

• Since the solution has 25 grams of dextrose per 100 mL, we can find the total grams of dextrose in 1500 mL by using a ratio:

[

\text{Total grams of dextrose} = \left(\frac{25 \text{g}}{100 \text{mL}}\right) \times 1500 \text{mL} = 375 \text{g}

]

2. Next, convert the grams of dextrose into calories. Dextrose provides approximately 4 calories per gram:

[

\text{Total calories} = 375 \text{g} \times 4 \text{calories/g} = 1500 \text{cal
