Question

This number: 4.188x10^22 particles —-1cm ^3 x particles —-14.374cm^3 is about is about to number of silicon atoms this number: 6.20x10^23 particles is about the expected number of particles the silicon cube what are the differences of the two numbers ?

Answer 1

We are given two volume values, each volume has a certain number of molecules. The second number 6.20 x10^23 corresponds to the avogadro number and is equivalent to one mole of silicon. The first number does not make a molecule, so it must be only a fraction of the molecule of silicon being measured.

That will be the diference between the two number. 6.20 x10^23 is equivalent to one molecule while 4.188x10^22 is not.
