A salt solution has a volume of 250 mL and contains 0.70 mol of NaCl. What is the molarity of the solution?

$2.8 M$

Explanation:

Molarity is a measure of the concentration of a substance expressed in the quantity of solute in moles per liter of solution:

$M = \frac{m o l s o l u t e}{L s o \ln}$

$250 m L$ is equal to $0.250 L$, so our molar concentration is

$M = \frac{0.70 m o l N a C l}{0.250 L s o \ln} = 2.8 M$
