What is the molarity of a solution that contains 17 g of NH3 (ammonia) in 0.50 L of solution? (Molar mass of NH3 = 17 g/mol)

First, understand that molarity (M) is defined as the number of moles of solute per liter of solution. The formula for molarity is: $M=\frac{n}{V}$, where $n$ is the number of moles of solute and $V$ is the volume of the solution in liters.
