Consider a situation in which 161 g of p4 are exposed to 176 g of o2. a.)what is the maximum amount of p2o5 that can theoretically be made from 161 g of p4 and excess oxygen? (i got 2.60 mol) b.)what is the maximum amount of p2o5 that can theoretically be made from 176 g of o2 and excess phosphorus? (i got 2.20 mol) c.)now, determine how many moles of p2o5 are produced from the given amounts of phosphorus and oxygen. (i got 2.20mol/ theoretical yield) is what i need d.)what is the percent yield if the actual yield from this reaction is 206g?
