# What is the molarity of 350 mL of HCl?

## Question:

What is the molarity of 350 mL of HCl?

## Molarity:

Molarity is the number of moles in a substance per volume of the liquid in liters. The equation we use for molarity is:

{eq}\begin{array}{*{20}c} {M = \dfrac{{\begin{array}{*{20}c} {Moles \ Solute} \\ \end{array}}}{{\begin{array}{*{20}c} {Liter \ Solution} \\ \end{array}}}} \\ \end{array} {/eq}

For example, there are 0.05 moles of sodium chloride (NaCl) in 500 ml of a 0.1 M NaCl solution.
