1 mole of any substance contains Avogadro's number.
So, 1 mole of O2= 6.023x10^23 molecules
3 mole of O2= 6.023x10^23x3 molecules
= 1.8069x10^24 molecules
Each molecule of Oxygen has 2 atoms.
therefore,
1.8069x10^24 molecules= 1.8069x10^24 x 2 atoms
= 3.6138x10^24 atoms.

Answer:
See explanation
Explanation:
An unbalanced chemical equation does not show equal number of atoms of each element on both sides of the reaction equation.
a) KOH + H3PO4 -----> K3PO4 + 3H20
b) Zn + AgCl -------> ZnCl2 + Ag
c) NaHCO3 → Na2CO3 + H2O + CO2
d) NH4NO2 ------> N2 + H2O
e) CO2 + KOH -----> K2CO3 + H2O
