Okay, a mole of potassium perchlorate contains 6.02x1023 formula units of potassium perchlorate, but you're asking about individual atoms. So, let's look at the formula: KClO3. That's 1 potassium, 1 chlorine, and 3 oxygens, for a total of 5 atoms per formula unit. Now, multiple 5 by Avogadro's number above, to get 30.1x1023, which simplifies to 3.01x1024 atoms.

Answer: The number of atoms in 1.0 moles of potassium perchlorate is [tex]3.011\times 10^{24}[/tex]

Explanation:

We are given:

Moles of potassium perchlorate = 1.0 moles

According to mole concept:

1 mole of a compound contains [tex]6.022\times 10^{23}[/tex] number of molecules.

1 mole of [tex]KClO_3[/tex] contains 1 potassium atom, 1 chlorine atoms and 3 oxygen atoms.

Number of atoms in [tex]KClO_3[/tex] = 5

So, 1.0 moles of potassium perchlorate will contain = [tex](1.0\times 6.022\times 10^{23})=3.011\times 10^{24}[/tex] number of atoms.

Hence, the number of atoms in 1.0 moles of potassium perchlorate is [tex]3.011\times 10^{24}[/tex]
