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.
