Hi there!
![\large\boxed{3.203 * 10^{22} atoms}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B3.203%20%2A%20%2010%5E%7B22%7D%20atoms%7D)
We can use the following conversions to solve:
Total mass --> amount of mols --> amount of atoms (Avogadro's number)
Begin by calculating the amount of boron trifluoride in 3.61 grams:
3.61 g * (1 mol BF₃ / 67.8 g) ≈ 0.0532 mol BF₃
Use avogadro's number to convert:
0.0532 mol * 6.02× 10²³atoms / 1 mol = 3.203 × 10²² atoms
A:2KClO3=2KCl+3O2 hope it helps ! Don't know the rest
