Five gross samples were determined for a carload of limestone. The average percent Mgo values for the gross samples were found to be 49.53, 50.12, 49.60, 49.87, and 50.49. Meanwhile, the following results were obtained for the determination of magnesium in a NIST magnesia sample: %MgO = 50.33, 50.22, 50.36, 50.21, and 50.44. Calculate the relative standard deviation associated with the sampling step.

A 0.9352g sample of ore containing Fe³+, Al³+ and Sr²+ was dissolved and made up to 500.00 mL. The analysis of metals was performed using complexation volumetry. Initially, an aliquot of 50.00 mL had its pH adjusted to 1.0 and titrated with a standard 0.03145 mol/L EDTA solution, requiring 6.95 mL to reach the end point. Subsequently, another 25.00 mL aliquot was buffered at pH=5 and titrated with the same EDTA solution, requiring 6.24 mL to reach the end point. Finally, a third aliquot of 25.00 mL was titrated at pH=11, requiring 11.10 mL of the same EDTA solution to complete the titration.
