Phosphoric acid can be prepared by reaction of sulfuric acid with "phosphate rock" according to the equation: Ca3(PO4)2+3H2SO4 ---> 3CaSO4 + 2H3PO4
What is the molar mass of Ca3(PO4)2?
How many oxygen atoms are there in 1.55mg of Ca3(PO4)2?
Suppose the reaction is carried out starting with 103 g of Ca3(PO4)2 and 75.0 g of H2SO4. Which substance is the limiting reactant?
