Reference no: EM131895372

One of the major uses of sulfuric acid is the production of phosphoric acid and calcium sulfate. The reaction is:

Ca3(PO4)2(s) + 3H2SO4(aq) → 3CaSO4(s) + 2H3PO4(aq) 

What mass of concentrated sulfuric acid (98.0 % H2SO4 by mass) must be used to react completely with 164.5 g of Ca3(PO4)2?

Enter your answer to four sig. fig.
