1. The problem statement, all variables and given/known data Find the mg of Fe in vitamin pill. Vitamin pill was dissolved in 25mL HCl which was then diluted to 250mL with water in flask. 25mL of that solution was then diluted to 100mL in another flask. 10mL of the second was diluted to 100mL in another flask. Absorbance of the last solution and standard solutions were taken and a calibration curve created. It was determined that the sample solution contained 12.0mg/L iron. Determine the number of mg of Fe in tablet. 2. Relevant equations 3. The attempt at a solution 12.0mg/L x 0.100L x (100mL/25mL) x (100mL/10mL)=48.0mg Fe in tablet I am not sure if I am correct. Do I need to account for the 25mL HCl diluted to 250mL as well? Any help in direction would be greatly appreciated! Thanks.
