calculate the molarity of a solution if there are 1.5 mol of NaCl in 2.3 L of solution

The solutions are homogeneous mixtures (that is, their properties and composition are uniform) of two or more substances. The substance that is in greater proportion is called solvent, and the substance or substances that are in a smaller proportion, solute.

The mole is an International Unit used to measure the amount of a substance.

Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a given volume of solution. It is expressed in the units (moles / liter).

[tex]Molarity=\frac{number of moles of solute}{solution volume}[/tex]

In this case, the solute is NaCl,and you know:

number of moles of solute: 1.5 mol
solution volume: 2.3 L

Then:

[tex]Molarity=\frac{1.5 mol}{2.3 L}[/tex]

Molarity≅0.6522 mol/L

The molarity of a solution if there are 1.5 mol of NaCl in 2.3 L of solution is 0.652M

HOW TO CALCULATE MOLARITY:

The molarity of a solution can be calculated by dividing the number of moles in the solution by its volume. That is;

Molarity = no. of moles (n) ÷ volume (L)

According to this question, there are 1.5 moles of NaCl in 2.3L of solution. The molarity can be calculated as follows:

Molarity = 1.5mol ÷ 2.3L

Molarity = 0.652M

Therefore, the molarity of a solution if there are 1.5 mol of NaCl in 2.3 L of solution is 0.652M.
