2. Calculate according the equation the mole of magnesiumcarbonate.
3. Calculate the molarity by using the given volume.

Once I do that and then what?

In the reaction represented below, 1.456x10^5 ug of V2(CO3)5 can produce 25.00 mL of what molarity MgCO3 solution?
V = 50.94 g/mol
C = 12.01 g/mol
O = 16.00 g/mol

Equation: 3V2(CO3)5 + 5Mg3(PO4)2 ----------> 15MgCO3 + 2V3(PO4)5

H3 PO4 + Ta(OH)5 = Ta(PO4)5 + H2O
