the number of atom present in the molecule is given by the Avogadro number that is 6.022×10²³ . For the CO2 , the molecule is made of 3 atom .So for the one mole of CO2 there are 1.8066×10²⁴ atom.
Answer:
The number before any molecular formula applies to the entire formula. So here you have five molecules of water with two hydrogen atoms and one oxygen atom per molecule. Thus you have ten hydrogen atoms and five oxygen atoms in total.
