Answer:
3542190029 0.2 moles number of molecules of carbon dioxide = 0.2× 6.022×10²³
= 1.2044×10²³
The number of oxygen atoms in one molecule of carbon dioxide = 2
∴ the number of oxygen atoms in 8.8 grams of CO₂= 1.2044×10²³×2
= 2.4088×10²³
mol
The atomic mass of oxygen = 16g/molg/mol
From the above,
The molar mass of carbon dioxide = 44g/molg/mol
∴Number moles of carbon dioxide present = \frac{8.8}{44}448.8 = 0.2 moles.
The number of molecules present in one mole = 6.022×10²³
in 0.2 moles number of molecules of carbon dioxide = 0.2× 6.022×10²³
= 1.2044×10²³
The number of oxygen atoms in one
0.2 moles number of molecules of carbon dioxide = 0.2× 6.022×10²³
= 1.2044×10²³
The number of oxygen atoms in one molecule of carbon dioxide = 2

Explanation:
Here we have 8.8 grams of carbon dioxide.
We know that,
The atomic mass of carbon = 12g/molg/
