# Which of the solutions below have the same molar concentration as solution x? check all that apply.

## General guidance

Concepts and reason
Molarity is the number of moles of solute in one liter of the solution. Mathematically, it can be expressed as follows:

Fundamentals

Concentration of a solution can be expressed in terms likes molarity, normality, molality, and mole fraction. Molarity and normality are the widely used terms to express the concentration of a solution. Avogadro number of particles is called as one mole.

## Step-by-step

### Step 1 of 2

Consider the following solutions:

Number of species in unit volume in solution X and solution A are equal.

In solution X, there are four species of solute in unit volume. In solution A, there are 4 species of solute, solution B has 8 species of solute and solution C has 2 species of solute.

### Step 2 of 2

If the number of moles present in unit volume increases, its concentration increases.

The number of moles of solution A is equal to the number of moles of solution X. Hence, the solution A has same molar concentration as solution X.

Solution B has more number of species than solution X. Hence, the molar concentration of solution B is higher than the solution X. Solution C has less number of moles in unit than solution C. Hence, the molar concentration of solution C is lower than the molar concentration of solution X.
