A solution is created using 2.1700 grams of Calcium Hydroxide (MW is 74.093) in a 1L volumetric flask. A 50 mL aliquot is then taken and aded to a 350 mL volumteric flask and filled to the line. Finally, a 10 aliquot of the that solution is taken and added to a 100 mL volumetric flask and diluted to the line. What is the concentration of OH ion in the final solution in mol/L? (answer to 4 decimal places)
