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.

How many moles is 0.75g of Na2CO3?
The formula mass of sodium carbonate, Na2CO3 is 2(23.0) + 12.0 + 3(16.0) = 106.0Amount of Na2CO3 = mass of sample/molar mass = 0.75/106.0 = 0.00708mol There are 0.00708 moles of Na2CO3 in a 0.75g pure sample.
How many atoms are in 0.5 mole of Ar?
6.226 x 10^28 atoms of Nitrogen approximately mole = 6.226 X 10^28 objects Nitrogen exists as a diatomic molecule, so in 0.5 moles of diatomic nitrogen gas there are exactly 1 moles worth of molecules, therefore the number of atoms in 0.5 moles of nitrogen gas is equal to the value of the mole which is approximately 6.226 x 10 ^ 28 atoms
