Please help to calculate a dilution factor and the amount of mg in the vitamin. There are 1.13 ppm of iron. An unknown vitamin was dissolved in 25 ml of 6 M of HCl. Then brought up to 100 mL with DI water. Dilute 5.00 mL of solution A to 100.0 mL in a 100.0-mL volumetric flask. This is Solution B.Transfer 10.00 mL of Solution B to a 100.0-mL volumetric flask. Based on this dilution, the dilution factor is 200, so how many mg of iron is in vitamin?

In the reactions below, there is a main reaction step followed by one or more workup steps (which are bold-faced). Briefly explain the purpose of the bold-faced workup step in both cases, based on your experience carrying out this reaction (or a similar reaction) in the lab. (MTBE= methyl tert-butyl ether) By means of an equation explain briefly what the purpose of step 2 in the work-up (shown in boldface) was in the synthesis of aspirin.
