You have an 80% dextrose solution. How many grams are in 75ml of solution?

To determine the number of grams of dextrose in a 75 ml solution of 80% dextrose, it's important to understand the concept of percentage concentrations. An 80% dextrose solution means that there are 80 grams of dextrose in every 100 ml of solution.

To find the amount of dextrose in 75 ml, you can set up a proportion based on the concentration. First, calculate how many grams of dextrose are in 1 ml of this solution:

80 grams dextrose / 100 ml solution = 0.8 grams dextrose per ml.

Next, multiply the grams per ml by the total volume of the solution (75 ml):

0.8 grams/ml × 75 ml = 60 grams of dextrose.

Thus, in 75 ml of an 80% dextrose solution, there are 60 grams of dextrose. This confirms that the answer is correct.
