Answer:
Option B, 2.167 x 1024 atoms
Explanation:
1 mole of CO2 = 44.01 grams
Number of moles of CO2 in 158.4 gram sample
[tex]\frac{158.4}{44.01} \\3.95[/tex]moles
Number of atoms in one mole is [tex]6.02*10^{23}[/tex]
Number of atoms in 3.95 moles [tex]2.167 *10^{24}[/tex]
Hence, option B is correct
