Answer 1

Heya folk !!

Here's the answer you are looking for

The molecular weight of CO2 is 44g

So, 1 mole of CO2 weighs 44g

It can be also written as,

44g of CO2 = 1mole = 6.022 × 10²³ molecules of CO2

So, 4.4g of CO2 = 0.1mole = 6.022 × 10²² molecules of CO2.

☛ In each molecule of CO2, there are 2 atoms of Oxygen.

☛ So, in 6.022 × 10²² molecules of CO2,
there will be 2 × 6.022 × 10²² atoms of Oxygen

= 12.044 × 10²² atoms

= 1.2044 × 10²³ atoms

= 1.2 × 10²³ atoms (approx.)

Thus, the answer is (C) 1.2 × 10²³ atoms.
