Answer:

To find the number of atoms in a given number of moles, you can use Avogadro's number, which is approximately 6.022 × 10^23 atoms per mole.

Let's calculate the number of atoms for each given mole:

1.5 moles of F:

Number of atoms = 1.5 moles * (6.022 × 10^23 atoms/mole)

= 9.033 × 10^23 atoms of F

0.5 moles of O:

Number of atoms = 0.5 moles * (6.022 × 10^23 atoms/mole)

= 3.011 × 10^23 atoms of O

1.25 moles of Sr:

Number of atoms = 1.25 moles * (6.022 × 10^23 atoms/mole)

= 7.5275 × 10^23 atoms of Sr

Therefore, there are approximately:

- 9.033 × 10^23 atoms of F in 1.5 moles of F

- 3.011 × 10^23 atoms of O in 0.5 moles of O

- 7.5275 × 10^23 atoms of Sr in 1.25 moles of Sr.

Keep in mind that these values are approximate due to the rounded value of Avogadro's number.
