How many grams of Ca are in 145 g of CaF2?
To find the grams of calcium (Ca) in 145 g of calcium fluoride (CaF2), first calculate the molar mass of CaF2. The molar mass of Ca is approximately 40.08 g/mol, and that of fluorine (F) is about 19.00 g/mol, so the molar mass of CaF2 is approximately 40.08 + 2(19.00) = 78.08 g/mol. The mass fraction of Ca in CaF2 is 40.08 g/mol / 78.08 g/mol ≈ 0.513. Therefore, in 145 g of CaF2, the mass of Ca is about 145 g × 0.513 ≈ 74.4 g.

How many grams of f are in 165 caf2 grams of?
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.
