To balance equation → number of atoms must be the same for both sides of reaction → add coefficients
Balanced: Ca3(PO4)2(s) + 3H2SO4(aq) → 3CaSO4(s) + 2H3PO4(aq)
Ca - 3 Ca –
P - 2 P -
12 20 O - 8 20

1 3 S - 1 3
mass H2SO4 = 980 g H2SO4
Determine limiting reactant → reactant that forms the less amount of product.
Mole to mole comparison:
