How to solve molarity steps
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 WebThis video explains how to calculate the concentration of the solution in forms such as Molarity, Molality, Volume Percent, Mass Percent, and Mole Fraction. It also explains how to calculate...

The mole fraction or molar fraction (xi) is defined as the amount of a constituent (expressed in moles), n i, divided by the total amount of all constituents in a mixture (also expressed in moles), n tot: x i = n i n t o t. The sum of all the mole fractions is equal to 1: ∑ i = 1 N n i = n t o t; ∑ i = 1 N x i = 1.
