What is the empirical formula of a compound which contains only phosphorus and oxygen if a 4.19 gram sample of the compound contains 1.83 grams of oxygen and 2.36 grams of phosphorus?
List the phosphorus first in your answer.
You will not be able to type subscripts. Just type the numbers where they go. For example, S2O3 would be typed in as S2O3.
