WebThe percentage of phosphorus can be obtained by assuming a 100.0 g sample; therefore it contains 30 g of P2O5. From this, the moles of P2O5 are calculated, converted to moles of phosphorus and then converted into mass of phosphorus (P). One finds that this gives 13 g of P in the 100 g sample; hence, 13% P.
