Question

number of oxygen atoms in 8 gram of ozone is

Answer 1

Molar mass of ozone is O3(16*3)=48 grams

No. Of moles of ozone in 8 gram of it =8/48 moles

So no.of moles of O is 3 times no. Of moles of O3 because each ozone molecules contains 3 atoms of O

N=3*8/48=0.5 moles

So no.of atoms can be calculated by multiplying no. Of moles by avogadro number as

0.5* 6.023×10^23=3.0115×10^23 atoms.

Hope it helps…

Answer 2

Answer:

Explanation:

Molecular mass of o3=48gm

No. Of moles of o3 in grams of it =8/48 gm

N=3×8/48

=0.5 moles

Its multiply with aewogedroy number so..

=0.5 ×6.022×10^23

=3.0115 × 10^23
