How many Tons of H2SO4 and Ca2(PO4)2 is required for produce 1 Ton of H3PO4??????????

Question

My question: Production of Phosphoric acid by wet process technology.

Main Raw materials: Sulfuric acid, Phosphate rock (calcium phosphate) and water gives Phosphoric acid and gypsum.

3H2SO4 Ca3(PO4)2 6H2O -> 2H3PO4 3 CaSO4.2H2O

We need the theoretical yield for Phosphoric acid.

how much quantity for raw materials required for produce 1 metric tone of phosphoric acid ??????????????????

Answer 1

3H2SO4 & Ca3(PO4)2 & 6H2O -> 2H3PO4 &  3 CaSO4.2H2O

--------------------------------------...

find the mass in grams, of what was in the reaction:

3 H2SO4   ..... (3moles) (98.078 g/mol) = 294.234 grams

Ca3(PO4)2 ,,,,  (1mole) (310.18 g/mol) = 310.18 grams

2 H3PO4   ....  ( 2 moles ) (98.0 g/mol) = 196 grams

--------------------------------------...

that ratio of grams reacts, just as would that ratio of tons:

3 H2SO4   ..... 294.234 tons

Ca3(PO4)2 ,,,, 310.18 tons

2 H3PO4   ....  196 tons

--------------------------------------...

How many Tons of H2SO4 is required to produce 1 Ton of H3PO4:

1 Ton of H3PO4 @  294.234 tons H2SO4/ 196 tons H3PO4 = 1.50

your answer is 1.50 tons of H2SO4 is required

How many Tons of Ca2(PO4)2 is required to produce 1 Ton of H3PO4:

1 Ton of H3PO4 @  310.18 tons Ca2(PO4)2 / 196 tons H3PO4 = 1.58

your answer is 1.58 tons of Ca2(PO4)2  is required

I am not rounding off for sig figs, i don't think they wanted it to be the  1 sig fig problem that "1 ton" made it
