Atomic Masses: Counting Atoms by Weighing
... To determine the number of oxygen molecules required, we must know how many carbon atoms are present in the pile of carbon. But individual atoms are far too small to see. We must learn to count atoms by weighing samples containing large numbers of them. In the last section we saw that we can easily ...
