Answer 1

We know that, ozone = O3


and molar mass of one Oxygen atom = 16

So molar mass of 3 oxygen atom = 16 × 3 = 48

Now we know that, mole
= weight (in gram)/molar mass

So mole of given ozone =

48/48 = 1 mole


Now we know the mole so we can calculate the number of atoms

We can see ozone is constituted of three atoms of oxygen.

So in 48grams no. of atoms =

Mole × atoms given × NA(Avogadro number)

=> number of atoms =

1 × 3 × 6.022 × 10²³

(Since NA = 6.022 × 10²³

=] Number of atoms =

= 18.066 × 10²³

Or we can write by moving decimal place to left as

1.8066 × 10²⁴


Hope it helps dear friend ☺️✌️
