A student weighed a fuel cup for a bomb calorimetry experiment and obtained 10.3729 g. She then added a benzoic acid pellet and reweighed, finding 11.2872 g. Using a type B approach she estimated a standard uncertainty of .0003 g. for each weighung. Find the mass of the pellet and its standard uncertainty.
