From a mineralogical perspective, fluorite is an evaporite mineral that contains one calcium ion and two fluorine ions. Calcium may also be substituted partially accounting for different colours of the mineral but it is usually purple.
The molecular mass of calcium fluoride is 78,07 g.
The formula is CaF2 so, its three atoms, one calcium and two fluorine atoms. add the molar mass of calcium(40 g/mol) and fluorine(19 g/mol X 2 because there are two atoms of fluorine) and you get 40+(19x2)=78 78 grams per mol
The chemical formula of barium fluoride is BaF2.
The formula mass of sodium fluoride, NaF is 23.0+19.0=42.0 Mass of 4.5mol of NaF = 4.5 x 42.0 = 189g
The formula mass of CaF2 is 40.1 + 2(19.0) = 78.1 Amount of CaF2 = 58.2/78.1 = 0.745mol
Calcium Fluoride is CaF2. Therefore, its molecular mass = mass(Calcium + 2 x Flourine) = 40 + 2x19 = 78 u.

The formula of sodium fluoride is NaF; its gram formula mass is 41.9882.
To find the formula weight you have to add each elements mass together. The formula for this compound is CaSO3. Ca:40.08 S:32.07 O:3X16=48 Total= 120.15 <---- this is the formula weight.
Calcium chloride with formula CaCl2 has molecular mass of 141. Commercial calcium chloride has formula CaCl2,2H2O.It's molecular mass is 177.
1 mole CaF2 = 78.074g CaF2 0.06mol CaF2 x 78.074g CaF2/mol CaF2 = 5g CaF2 (rounded to 1 significant figure)
