You have an 80% dextrose solution. How many grams are in 20ml of solution?

To determine how many grams of dextrose are in a 20 ml solution of 80% dextrose, you can use the concept of percentage concentration. An 80% solution means that there are 80 grams of dextrose in every 100 ml of the solution.

First, calculate the amount of dextrose present in 20 ml of solution:

1. Find the grams of dextrose per milliliter:

Since there are 80 grams in 100 ml, you can find the amount per ml by dividing 80 by 100. This results in 0.8 grams of dextrose per ml.

2. Multiply the grams per ml by the volume in ml (20 ml):

0.8 grams/ml * 20 ml = 16 grams.

Thus, in a 20 ml solution of 80% dextrose, there are 16 grams of dextrose. This makes the 16 grams the correct answer, as it reflects the proper calculation of grams based on the percentage concentration and given volume.
