Hola Issac,
Remember that every MOLE of atoms is 6X10^23 atoms.
MOLE is like a quantifier (dozen = 12, carton =24). Mole = 6X10^23
So 0.125 mole of oxygen molecules is
0.125 X 6 X 10^23 = 7.5 X 10^22 molecules.
Each oxygen molecule has 2 atoms (O2). So 0.125 mole of oxygen molecules have
7.5 X10^22 X 2 = 1.5 X 10^23 atoms
Concept! =)
