Question

If I use 2 mol NaOH to make 1 liter of solution, what is the molarity of the solution?

Answer 1

The molar concentration of the solution is defined as the ratio of the number of the moles of the solute to the volume of the solution:

$c= \frac{n}{V}$ .

Therefore, the molarity of the sodium hydroxide solution is:

$c = \frac{2}{1} = 2$ mol/L, or 2 M.

Answer: the molarity of the solution is 2 M.
