A 1.345 gram sample of a compound containing barium and oxygen was dissolved in hydrochloric acid to give a solution of barium ions (Ba+2), which was then completely precipitated out with excess potassium chromate to give 2.012 grams of barium chromate, BaCrO4.   (a) How many moles of barium ions(Ba+2) were in the original sample? (b) How many grams of barium ions (Ba+2) were in the original sample? (c) How many grams of oxygen ions(O-2) were in the original sample? (d) What is the percentage by mass of O ions (O-2) in the original(1.345g) sample?
