4) Consider the following procedure. A vitamin containing 0.190 + 0.002 g of iron is dissolved in acid. The acid and dissolved vitamin are transferred to a Class A 100 mL volumetric flask and diluted to 100 mL with DI water. From this solution, 1 mL is removed using a Class A, 1 mL volumetric pipet.
This 1 mL aliquot is transferred to a second-Class A, 100 mL volumetric flask and diluted to 100 mL using DI water. What is the absolute uncertainty in the solution's concentration? What is the concentration of the iron in the final solution? What measurement uncertainty has the greatest influence on the density's uncertainty?
