hey miss
here is ur answer
▶▶▶▶▶▶▶▶▶
In 44g of CO2 oxygen atoms are 2Na [where Na is avagadro no.] ∴ Number of oxygen atoms in 4.4g is 0.2Na = 0.2 * 6.022 * 10^23.
= 1.20 * 10^23 atoms

I hope this will help

Hii..
See ...molar mass of CO2=44g(one mole)
Number of moles in 4.4g =0.1
In 44g the number of oxygen atoms are
2 ×6.022×10²³(2atoms of oxygen)
So in 4.4g of CO2
oxygen atoms =0.1×2×6.022×10²³
=1.20×10²³
hope this helps!

see as in one mole CO2 there are 2 atoms of oxygen
"CO2"
