If a solution contains 5% concentration, how many grams are in 100ml?

To determine how many grams are in a 100 mL solution with a 5% concentration, you can start by understanding how percentage concentration is calculated. A percentage concentration of 5% means that there are 5 grams of solute (the substance being dissolved) in every 100 mL of solution.

Therefore, for a 100 mL solution with a 5% concentration, you directly calculate:

5% of 100 mL = 5 grams

This means that in 100 mL of a solution with a 5% concentration, there are exactly 5 grams of solute present. This aligns perfectly with the requested outcome, confirming that the correct answer is indeed 5 grams.
