A food supplement is analyzed by Atomic Absorption Spectroscopy to know its Ca content. A 10 ppm standard registers an absorbance of 0.448. A 4.45 g sample is calcined, the ashes are dissolved with 10 mL of acid, and the solution is finally made up to 50 mL; the absorbance reading was 0.325. How many mg of Ca are in 100 g of the dietary supplement?
