The solution concentration that is expressed in terms of molarity is as follows:
[tex]\boxed{{\text{D}}{\text{. 10 mol of solute/1 L of solution}}}[/tex].
Further Explanation:
Concentration describes relationship between different components of solution. In order to indicate concentration of different types of solutions, various concentration terms are used. Some of these are mentioned below.
1. Molarity (M)
2. Mole fraction (X)
3. Molality (m)
4. Parts per million (ppm)
5. Mass percent ((w/w) %)
6. Volume percent ((v/v) %)
7. Parts per billion (ppb)
A. 10 g of solute/1000 g of solution
Mass percent is defined as the ratio of mass of solute to that of solution. Since above expression is the ratio of mass of solute to mass of solution, it is expressed as mass percent and not molarity.
B.10 g of solute/1000 mL of solution
Density is defined as mass per unit volume. Since above expression is the ratio of mass to volume, it is expressed as density and not molarity.
C. 10 mL of solute/1 L of solution
Volume percent is defined as the volume of solute divided by the total volume of solution. Since above expression is the ratio of volume of solute to volume of solution, it is expressed as volume percent and not molarity.
D. 10 mol of solute/1 L of solution
Molarity is defined as moles of solute that can be dissolved in one liter of solution. Since above expression is the ratio of amount of solute to the volume of solution in liters, it is expressed as molarity of solution.
Hence, option D represents the solution in terms of molarity.
