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.
[tex]\text{Concentration of solution}=\frac{\text{Mass of solute}}{\text{100 mL volume of solvent}}[/tex]
Now put all the given values in this expression, we get:
[tex]\text{Concentration of solution}=\frac{25g}{\frac{40}{100}mL}=62.5g/100mL[/tex]
Thus, the concentration of solution is, 62.5 g/100 mL
