Fluorine is produced chiefly from fluorite, CaF2. Fluorine can also be obtained as a by-product of the production of phosphate fertilizers, derived from phosphate rock [ 3 Ca3 (PO4)2 . CaF2] . What is the maximum mass of fluorine that could be extracted as a by-product from 1200 of phosphate rock?

Convert g rock to moles rock (tricky. Total rock formula weight is
3 x [Ca3(PO4)2)] + CaF2.
How many moles F atoms? (Care!) Then multiply by at. mass of F.
ALL these problems balancing amounts of one substance with another involve (a) going through moles, (b) using mole ratio from formula or from balanced equation.
Good luck!
