The concentration of a solution is equal to the mass of solute divided by the volume of solvent. Units of concentration are grams per 100 milliliters (g/100 mL, or g/dL). What is the concentration of this solution?

This is an incomplete question, here is a complete question.

The concentration of a solution is equal to the mass of solute divided by the volume of solvent. Units of concentration are grams per 100 milliliters (g/100 mL, or g/dL). What is the concentration of this solution, if 25 g of solute dissolved in 40 mL of water?

Answer : The concentration of solution is, 62.5 g/100 mL

Explanation : Given,

Mass of solute = 25 g

Volume of solvent (water) = 40 mL

Now we have to calculate the concentration of solution.

Now put all the given values in this expression, we get:

Thus, the concentration of solution is, 62.5 g/100 mL
