How many grams of carbohydrates are in a cup of dextrose solution if the solution contains 5% dextrose?

To determine the number of grams of carbohydrates in a cup of a 5% dextrose solution, it's important to start with the known volume of the solution and the percentage concentration of dextrose.

A standard cup measurement is approximately 240 milliliters. A 5% dextrose solution means that there are 5 grams of dextrose in every 100 milliliters of solution.

To calculate the total amount of dextrose in 240 milliliters, you can set up a proportion based on the 5% concentration. Since 5 grams is present in 100 milliliters, to find out how much is in 240 milliliters, you can use the following calculation:

[

\text{Dextrose in 240 ml} = \left( \frac{5 \text{ grams}}{100 \text{ ml}} \right) \times 240 \text{ ml} = 12 \times 5 = 60 \text{ grams}

However, this calculation indicates there may have been an error initially interpreting or presenting the options, as the results of 60 grams do not correspond to the given choices directly.

In this case, the closest understanding would
