How do you find molarity from mole fraction and density?

1. Relationship b/w Molarity(M) or molality(m): m=1000×M/1000×D-M×Molar mass of solute. Where D is density .
2. Rel.b/w. molality(m) and mole fraction (X): m=1000×X of solute /X of solvent × molar mass of solvent.
3. Rel. b/w M and X of solute:
4. M ,when density is given:-

How many moles of KNO3 should 1.0 L of stock solution contain?

0.500 moles
Molarity is measued in moles per liter, mol L−1 , or molar, M , which means that a 0.500-M solution will contain 0.500 moles of potassium nitrate for every 1 L of solution.

How do you find the molarity of KMnO4 solution?

Calculate the molarity of a solution prepared by dissolving 23.7 grams of KMnO 4 into enough water to make 750 mL of solution. This example has neither the moles nor liters needed to find molarity, so you must find the number of moles of the solute first.

What is the molarity if there is no density?

If you were onlygiven two of these: (1) mass percent or (2) molality or (3) mole fraction (and no density), you could not get the molarity (or the density). However, suppose you are given one of these: (1) mass percent or (2) molality or (3) mole fraction and then also given molarity instead of the density.

How do you calculate molarity from concentration?

Molarity formula. The following equation will allow you to find the molarity of a solution: molarity = concentration / molar mass. The concentration denotes the mass concentration of the solution, expressed in units of density(usually g/l or g/ml). Molar mass is the mass of 1 mole of the solute.

How do you calculate liters of solution from 1 mol of NaOH?

Solution: 1 mol of NaOH has a mass of 40.00 g, so. #”Moles of NaOH” = 15.0 cancel(“g NaOH”) × “1 mol NaOH”/(40.00 cancel(“g NaOH”)) = “0.375 mol NaOH”#. #”Litres of solution” = 225 cancel(“mL soln”) × “1 L soln”/(1000 cancel(“mL soln”)) = “0.225 L soln”#.
