A 0.928 g cereal sample was digested in acid and diluted to a final volume of 20.0 mL. It was then subjected to a further 10-fold dilution. When that solution was evaluated using ICP-MS, a particular element was present at 258.9 ppb (wg/L). How many milligrams of the element were present in the cereal sample? Enter the numerical value as a number ( 0.0315 mg as 0.0315). Note: The question is asking for milligrams in the sample not milligrams element...
