Hi im reviewing gen chem for DAT and i came along this problem, its not that hard and i did bunch of them, but im stuck on this one(its from 1001Q in GC, q#93),
"The mass percent of a compound in as follows:43.64% P, and 56.36%O. What's the empirical formula of the compound?" The correct answer is P2O5, but no matter how i do it i cant get this result. Any help how to get to that result? They say to work the problem backwards, but how would i know if i need to work it backwards or not on the actual DAT?
