How Many Atoms Of Oxygen Are Present In 6.00 Grams Of Kclo3 Do Cats Steal Your Soul ?

The formula for kClO3 is KClO3. A molecule of KClO3 contains one atom of chlorine, one atom of potassium and three atoms of oxygen.

There are 6.00 grams in 1 mole of KClO3. So the number of moles in 6.00 grams is 6.00 grams/mole = 0.100 mol

Each mole contains Avogadro’s constant number of molecules, N A , so there are 0.100 mol x N A = 0.100 x 6.02 x 1023 = 602,000,000 molecules

The number of atoms in a molecule is equal to the number of protons plus neutrons divided by the atomic mass of an atom (the sum of protons and neutrons). In this case there are 6 protons and 4 neutrons so there are 12 particles per molecule:

602,000,000 molecules x 12 particles per molecule = 7,424,000,000 particles.
