Phospheric  acid `(H_(3)PO_(4))` perpared  in two    step  process .     (1)  `P_(4)+5O_(2) to P_(4)O_(10)"                     "(2) P_(4)O_(10) + 6H_(2)O to 4H_(3)PO_(4)`   Well  allow   62 g of phosphrous to  react with  exces  oxygen  which  from  `P_(4)O_(10)`  in `85%` yield  . In  the sep (2) reaction `90%`  yield  of `H_3)PO_(4)` is obtained . Mass of `H_(3) PO_(4)` produced is :
