Moles and Molarity For acid-base chemistry purposes, it is more appropriate to measure solute concentration inmoles,or individual particles (e.g., atoms, molecules), per unit volume rather than mass per unit volume. This is because atoms react with each other in known proportions in a way un...

Calculate the molarityof a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof thesolutefirst. ...
(Molar mass of sucrose = 342.30 g/mol)How much sucrose do you need to make 50 ml of a 10% solution? Sucrose is a solid with a molecular weight of 342.3.What is the molarity of a sucrose solution that contains 76.7 g of C12H22O11 (342.34...
Step 3.Divide the moles of solute found in Step 1 by the liters of solvent found in Step 2 to find the initial concentration of a solution. The equation looks like this: M = 0.50 mol NaOH/0.500 L solvent = 1 M NaOH. In this example, the molarity (M) of the NaOH in the solvent...
In a titration of a sample of HCl(aq) with 0.113 M NaOH(aq), it took 51.2 mL of the base to reach the endpoint of the titration. Calculate the number of moles of the acid being neutralized. What is the molarity of the acid given 18.2 mL of HClO4 is neutralized in a titration by...
