Preparation of Middle Distillate SRM Blends

The video tutorial explains the process of preparing a sulfur concentration standard using a log-log chart. It details the preparation of a standard near the EPA regulatory limit using SRM 2770 and RM-8771. The tutorial covers weighing and mixing components, handling SRM 2770 and RM-8771, and calculating the final sulfur concentration. The goal is to achieve a concentration close to 14 PPM with an uncertainty of 0.13 PPM.

What was the final weight of the solution after combining both components?

How is the sulfur concentration calculated in this experiment?

What uncertainty is associated with the final concentration of the standard prepared?
