Answer:

195

Explanation:

First, calculate the molar mass of CaF2:

Ca: 1 × 40.078 g/mol = 40.078 g/mol

F: 2 × 18.998 g/mol = 37.996 g/mol

40.078 g/mol + 37.996 g/mol = 78.074 g/mol CaF2

Then, convert moles to grams by multiplying the number of moles by the molar mass:

2.50 mol CaF2 × 78.074 g/mol CaF2 = 195 g CaF2

Answer:

195.199grams

Explanation:

Fluorine has a molar mass of 18.99984 while calcium has a molar mass of calcium is 40.08.

1 mole of  calcium fluoride has a mass of 40.08+2×18.99984

=78.0797 grams

if one mole has a mass of 78.0797 grams, then 2.5 moles have:

2.5 moles× 78.0797 grams/mole= 195.1992 grams
