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
