1. What mass of Ca3(PO4)2 is produced if 750 mL of 6.00 M H3PO4 react according to the following reaction?
H3PO4 + Ca(OH)2 --> Ca3(PO4)2 + H2O
2. Using the reaction above, how many liters of 5.00 M H3PO4 are needed to produce 4390 g of Ca3(PO4)2?
3. If 75 mL of AgNO3 solution reacts with enough copper (II) to produce 0.25 g of Ag in a single displacement reaction, what is the molarity of the initial AgNO3 solution?
4. Suppose that 48 mL of 0.395 M Na2SO4 are added to Ca(NO3)2 to produce NaNO3 and CaSO4. Find the mass of CaSO4 produced.
