Calculate the molarity of each of the following solutions. Use the periodic table if necessary. A salt solution with a volume of
Andru [333]

The molarity of the NaCl in the 250 ml slat solution is 2.8M.

<h3>What is molarity?</h3>

The molarity of a solution is defined as the concentration of a solute per unit volume of the solution.

Given, the volume of the solution is 250 ml converted into l 0.25

The number of moles of NaCl is 0.70.

By the formula  of molarity

M = \dfrac{n}{V}\\\\\\M = \dfrac{0.70}{0.25} = 2.8 M

Thus, the molarity is 2.8 M.
