The molecular mass of calcium fluoride is 78,07 g.
Calculate the number of moles of calcium fluoride by dividing the mass by its molar mass. The molar mass of calcium fluoride (CaF2) is 78.08 g/mol. Then, multiply the number of moles by Avogadro's number (6.022 x 10^23) to find the number of atoms present in 7.92g of calcium fluoride.
To find the number of moles, you first need to determine the molar mass of calcium fluoride, which is 78.07 g/mol. Then, divide the given mass by the molar mass: 12.8 g / 78.07 g/mol = 0.164 moles. Therefore, there are 0.164 moles in 12.8 g of calcium fluoride.
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 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 molecular mass of calcium fluoride is 78,07 g.
Calcium Fluoride is CaF2. Therefore, its molecular mass = mass(Calcium + 2 x Flourine) = 40 + 2x19 = 78 u.
To calculate the number of moles in calcium fluoride, you need to divide the given mass (58.2 g) by the molar mass of calcium fluoride (about 78.08 g/mol). Dividing 58.2 g by 78.08 g/mol gives you approximately 0.746 moles of calcium fluoride.

The formula of sodium fluoride is NaF; its gram formula mass is 41.9882.
To find the grams of F in 165 g of CaF2, you need to consider the molar mass of CaF2. Calcium (Ca) has a molar mass of about 40.1 g/mol, and fluorine (F) has a molar mass of about 19 g/mol. So, the molar mass of CaF2 is about 40.1 + (19 x 2) = 78.1 g/mol. Then, you can calculate the grams of F in 165 g of CaF2 by determining the proportion of F in the compound CaF2 compared to its total molar mass.
The balanced chemical equation for the reaction between calcium carbonate and aluminum fluoride is: CaCO3 + 2AlF3 -> CaF2 + Al2(CO3)3. To determine the grams of each product produced, you need to first calculate the limiting reactant then use stoichiometry to find the grams of each product formed.
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)
