P = 56.35 & O = 43.65 ( Total is 100 %)
Divide each by their elemental mass
P = 56.35/31 & O = 43/65 / 16
P = 1.817 & O = 2.728
Take the lowest ratio and divide into itself and into the other ratio(s).
P = 1.917/1.817 = 1
O = 2.728 / 1.817 = 1/5051...
Hence ratios are P : 1 :: O 1.5
In whole numbers. by multiplying by 2.
P = 2 :: O = 3
Hence empirical formula is P2O3
P underscore 2 O underscore 3
P2o3
