# A pipet is used to transfer 5.00 mL of a 1.25 M stock solution in flask “S” to a 25.00-mL volumetric flask “B,” which is then diluted with DI H2O to the calibration mark. The solution is thoroughly mixed. Next, 3.00 mL of the solution in volumetric flask “A” is transferred by pipet to a 50.00-mL volumetric flask “B” and then diluted with DI H2O to the calibration mark. Calculate the molarity of the solution in volumetric flask “B.”

Step 1

Molarity can be defined as the ratio of number of moles of solute present in a solution to the total volume of the solution in L.

Step 2

Let the number of moles of stock solution transferred from flask S to the volumetric flask A be n1. The value of n1 can be calculated as follows-

Step 3

0.00625 mol of stock solution is transferred from flask S to flask A. The solution is further diluted by the addition of water and the final volume of th...
