The final molarity is given by the expression. If 50.00 mL of 0.100 M HCl are added to 100.00 mL of 0.400 M HCl and the mixture is diluted to a final volume of 500.00 mL, the final molarity will be. Solution 1 (0.100 M HCl)(0.05000 L) = 5.00x10-3 mol HCl. Solution 2 (0.400 M HCl)(0.1000 L) = 4.00x10-2 mol HCl. Total moles = 4.50x10-2 mol HCl ...

What is the molarity, molality and mole fraction of HCl? Begin with the assumption of 100 g of solution. With this assumption, you now know a few other facts. In 100 g of solution, 37.0 g is due to HCl (grams of solute) and 63.0 g is due to water (grams of solvent). To find molarity, we need to determine the moles of HCl (solute) per liter of ...

The equation for molarity states that the molarity of a solution is equal to the number of moles of solute divided by the number of liters of solution. In the first solution, the molarity will clearly be equal to 1.0M because there are 1.0 moles of NaCl and a solution volume of 1.0 L.
