WebStep 1/3 To solve this problem, we need to first calculate the mass of NH3 and water in the solution: Let's assume we have 100 g of the solution, then: Mass of NH3 = 16.70% x 100 g = 16.7 g Mass of water = 100 g - 16.7 g = 83.3 g Next, we need to convert the mass of NH3 to moles: Moles of NH3 = 16.7 g / 17.031 g/mol = 0.980 mol WebThe basic chemical formula to determine the molarity of a given solution is given as follows: Molarity = number of moles of a solute / litres of a solution M = n / V Where; M = molarity of the solution; n = number of moles of solute; V = volume of the solution.
