Phosphoric acid `(H_3PO_4)` prepared in a two step process. (1) `P_4+5O_2rarrP_4 O_10` (2) `P_4 O_10+6H_2Orarr4H_3 PO_4` We allow `62g` of phosphorus to react with excess oxygen which form `P_4 O_10` in `85%` yield. In the step (2) reaction `90%` yield of H_3PO_4` is obtained. mass of `H_3PO_4` produced is :
