Difference between mole and molecules

WebHere we are taking hydrogen atoms and oxygen atoms (left) to make water molecules (right). However, there are not enough oxygen atoms to use up all the hydrogen atoms. We run out of oxygen atoms and cannot make any more water molecules, so the process stops when we run out of oxygen atoms. Chapter 5 Stoichiometry and the Mole 273 WebThe number of sodium atoms present = 1. The number of chlorine atoms present = 1. Mass of a sodium atom = 989770 amu. Mass of an oxygen atom = 45 amu. Therefore the molecular weight of H 2 O = (1x 99 amu) + (1 x 35.45 amu) = 58.44 amu. With the help of the above example, we can say that both molar mass and molecular mass are the same …
