You have an 80% dextrose solution. How many grams are in 50ml of solution?

To find out how many grams of dextrose are in 50 mL of an 80% dextrose solution, you consider that an 80% solution means there are 80 grams of dextrose in every 100 mL of solution.

To calculate the amount in 50 mL, you can set up a proportion based on the concentration. Since 100 mL contains 80 grams, you can determine how many grams are in 50 mL by using the formula:

[

\text{grams of dextrose} = \text{concentration} \times \text{volume}

]

Substituting the values gives:

[

\text{grams of dextrose} = 0.80 \times 50 \text{ mL} = 40 \text{ grams}

]

Thus, there are 40 grams of dextrose in 50 mL of an 80% dextrose solution. This calculation confirms that the correct answer reflects the true amount of dextrose based on its concentration and the specific volume used.
