If a fertilizer bad is labeled 10-30-10, what is the percent phosphorus if they actually measured diphosphorus pentoxide? In a 15.00 g sample of fertilizer that is 10-30-10 how many grams of pure phosphorus do you expect if the label is accurate, and how many grams of phosphorus do you expect if the label measures diphosphorus pentoxide?

A. when phosphorus trihydride (also called phosphine) and oxygen gas react under the appropriate conditions the products of the reaction are diphosphorus pentoxide and water. If a 40.000 gram sample of phosphorus trihydride and a 40.000 gram sample of oxygen gas react, how many grams of diphosphorus pentoxide may be produced? (please show work and significant figures) B. Assume the percent yield for this reaction is 98.1 percent. If you want to actually produce 80.000 grams of diphosphorus pentoxide using...
