[NaNO₃] = 0.70 M

Explanation:

Molarity is a type of concentration for solutions. The unit is M but we can also find it as mol/L. It gives us the information about the moles of solute, contained in 1L of solution.

Solute: NaNO₃ → Moles = 1.4

Volume of solution 2L

Molarity = 1.4 mol/2L → 0.70 mol/L
