From the Fe2+ concentrations given determine the mg of Fe in the original vitamin tablet. You will need to convert ug/mL into mg of iron. You also have to consider that the original vitamin tablet sample was diluted to 250mL in a volumetric flask and then 5mL of that sample was diluted to 100mL in a volumetric flask. Please show all equations used and work done. 1. Concentration of 0.141738 2. Concentration of 0.1307058 3. Concentration of 0.1354047

A 100 mg vitamin C tablet weighed 1.627 g. A student crushed the tablet and transferred 0.159 g of the crushed powder into a 100 mL volumetric flask, dissolved the powder in ~30 mL DI water, then filled the flask to the calibration line with DI water and mixed well to create Solution 1. The student then transferred 23.2 mL of Solution 1 into a 100 mL volumetric flask and diluted to the calibration line with DI water to create...
