FREE Expert Solution

We’re being asked to calculate the molarity of a solution that contains 17 g of NH3 in 0.50 L of solution.


Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters)

In other words:

Molarity(M)=moles of soluteLiters of solution


Step 1: Calculate the moles of NH3.

Mass of NH3 (molar mass of NH3)  Moles of NH3\
