You have a 5% dextrose solution. How many ml will give you 18g of dextrose?

To determine how many milliliters of a 5% dextrose solution are needed to obtain 18 grams of dextrose, you can use the concept of concentration percentage. A 5% solution means that there are 5 grams of dextrose in every 100 milliliters of the solution.

To find out how many milliliters of the solution are required to get 18 grams of dextrose, you can set up a proportion based on the definition of the percentage:

5 grams of dextrose is contained in 100 ml of solution. Therefore, 18 grams of dextrose can be represented as follows:

If 5 grams corresponds to 100 ml, then 18 grams will correspond to X ml, and you can express this relationship mathematically as:

(5 g / 100 ml) = (18 g / X ml)

Cross-multiplying gives you:

5X = 18 * 100

Solving for X:

5X = 1800

X = 1800 / 5

X = 360 ml

Thus, to get 18 grams of dextrose from a 5% solution requires 360 ml of the solution. This supports the answer provided
