Examples of such places include Arizona, California and Oregon; where copper (and some other metals in some cases like gold in Oregon) is heavily mined and silver is recovered as a byproduct.
<span>2.8 carat C x (0.20g C/ 1 carat C) x (1 mole C/ 12.01 g C) x (6.02 x 10^23 atoms C/ 1 mole C) = 2.8 x 10^9 atoms C
Use factor label method in order to determine the amount of atoms, make sure the units cancel.</span>
In your equation, the molecule Ca3(PO4) is not possible. I believe you just forgot the 2 after the PO4.
If that is the case, the coefficients would go as follows:
3, 2, none, 6
