Question

In which of the following is the solution concentration expressed in terms of molarity?

Answer 1

Answer:
D. 10 mol of solute/ 1L of solution

Explanation:
Molarity is used to express the concentration of the solution. It is expressed as the number of moles of solute per liter of solution

Molarity = moles of solute / liters of solution
This means that molarity has the units moles/liter

The only option satisfying this is the last one.

Hope this helps :)

Answer 2

The solution concentration that is expressed in terms of molarity is as follows:

$\boxed{{\text{D}}{\text{. 10 mol of solute/1 L of solution}}}$.

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.
