1. When preparing the standard solutions, 1.00,2.00, 4.00 and 6.00mL of 50.0ppmFe2+ stock solution are pipetted into four 50.0mL volumetric flasks and diluted to the marks to make Standards 1-4, respectively. What is the concentration of each standard? Copy the final answers onto the data sheet for use in your post-lab calculations. 2. 25.00mL of a stock solution of sodium is pipetted into a 250.0mL volumetric flask and diluted to the mark ("Dilution 1"). 5.00mL of that solution is pipetted into a 25.0mL volumetric flask and diluted to the mark ("Dilution 2"). This solution is found to have a sodium concentration of 3ppm. a. What is the dilution factor for Dilution 1? b. What is the dilution factor for Dilution 2? c. What is the soncentration of sodium in the stock solution in ppm
