How many atoms of oxygen are there in one mole of carbon dioxide?

Question:   How many atoms of oxygen are there in one mole of carbon dioxide?


Answer:

The number of molecules is equal to 6.02 x 1023, which is true for one mole of any substance.  To figure out the
number of atoms, you need to multiply the number of molecules by the number of atoms of oxygen per molecule of carbon dioxide.  Since there are two atoms per CO2, simply multiply by 2 to get 1.204 x 1024.
