What is the concentration of 50grams per 100milileter water mean?

The concentration of 50 grams per 100 milliliters of water means that there are 50 grams of solute dissolved in 100 milliliters of water. This is also known as a 50% (w/v) solution, where "w/v" stands for "weight/volume." In other words, 50 grams of solute are present in every 100 milliliters of solution.

This concentration can also be expressed as 500 grams per liter (g/L) solution, since there are 1000 milliliters in a liter. Therefore, the concentration of the solution is 500 g/L.
