Final answer:
To find the mass of calcium phosphate, balance the equation and calculate the molar ratio between calcium chloride and calcium phosphate. Then, multiply the moles of calcium phosphate by its molar mass.
Step-by-step explanation:
In order to find the mass of calcium phosphate (Ca3(PO4)2) from the amount of calcium chloride (CaCl2), you need to use stoichiometry to balance the equation and calculate the molar ratio between the two compounds.
The balanced equation is: 3 CaCl2 + 2 Na3PO4 → Ca3(PO4)2 + 6 NaCl
From the balanced equation, we can see that the molar ratio between CaCl2 and Ca3(PO4)2 is 3:1. Therefore, if you have the amount of moles of CaCl2, you can determine the amount of moles of Ca3(PO4)2. To find the mass, multiply the moles of Ca3(PO4)2 by its molar mass.
