Question

which contains more molescules 0.5 mol of o2 or 0.5 mol 03. ?

Answer 1

Hey, there!

Here's the answer.

1 mole of a compound contains Na number of molecule.

So, 0.5 moles of O2 contains 0.5×Na number of O2 molecules.

Similarly, 0.5 moles of O3 contains 0.5×Na number of O3 molecules.

Thus, both of them contain same number of molecules.

But if you compare the number of atoms of O in 0.5 moles of O2 and O.5 moles of O3, then 0.5 moles of O3 Will have more number of atoms as both of them have same number of molecules and each molecule of O2 has 2 O atoms whereas each of OR molecule has 3 O atoms.
So, 0.5 moles O3 has more atoms than 0.5 moles of O2.

Hope that helps.

Thanks.
