Final volume = volume HCl + Volume H2O. 500mL = 20.8mL + Volume H2O. 479.2mL = Volume H2O. 2. Enough water is added to 350mL of 0.75M KOH to bring the volume to 600mL. Find the molarity of the new solution. 0.75M (350mL) = M2 (600mL) 0.44 M = M2 ***3. Find the molarity of a solution prepared by adding 125mL of water to 375mL of 2.0M KNO3 solution.

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 ...

Confirm that the molarity of the resulting is approximately 3.87 M. (Hint: first find the moles of salt present before the additional 275 mL of water was added by using equation #2 and then find the new molarity using equation #1.) Calculate the molarity of the solution formed by taking 350 mL of 2.25 M HCl and adding 420 mL of water.

Since the moles of solute (HCl) and volume of solution in liters is now know, calculate the molarity (M) as the moles of solute per liter of solution: From the information above, let's find the molality of the HCl solution. The moles of solute are already known (1.01 mol HCl). We need to find the kilograms of solvent:

Using plain ol’ stoichiometry, you should find that it will require 0.0135 moles of HCl to react with 5.00 g Ca(OH)2. Using the equation M = mol/L, this translates to 0.135 L of 0.100 M HCl. 3) If I combined 15.0 grams of calcium hydroxide with 75.0 mL of 0.500 M HCl, how many grams of calcium chloride would be formed? 2.08 grams
