Answer: The concentration of this solution is [tex]114g/dm^3[/tex]
Explanation:
Concentration of a solution is defined as the number of grams of solute dissolved per liter of the solution.
Given : mass of solute = 28.4 g
volume of solution = [tex]250cm^3=0.25dm^3[/tex] [tex]1cm^3=0.001dm^3[/tex]
[tex]Concentration=\frac{28.4g}{0.25dm^3}=114g/dm^3[/tex]
Thus the concentration of this solution is [tex]114g/dm^3[/tex]
By definition and change of units, the concentration of this solution is 113.6 [tex]\frac{grams}{dm^{3} }[/tex].
Chemical concentration determines the ratio of solute and solvent in a chemical solution and is defined as the ratio of the amount or volume of solute to the amount of solution. The more solute, the higher the concentration in a solution.
In this case, you know:
mass of solute= 28.4 g
volume of solution= 250 cm³= 0.25 dm³ (being 1 cm³= 0.001 dm³)
Then, the concentration can be calculated as:
[tex]concentration= \frac{28.4 grams}{0.25 dm^{3} }[/tex]
Concentration= 113.6 [tex]\frac{grams}{dm^{3} }[/tex]
Thus the concentration of this solution is 113.6 [tex]\frac{grams}{dm^{3} }[/tex].
