Rajinish,
Not all new-borns have exact same number of bones. So I should not expect anybody to give the exact figure. But it is true that it is more than 206 and 270 is a good approximation.
So, 5 points to you.

atomic mass is total mass of an atom i.e mass of proton, electron and neutron combined of that atom. It is expressed in unit called Atomic mass unit(AMU). whereas Atomic mass number is total number of proton and neutrons in nucleus of that atom. Atomic mass number= number of neutron+ number of proton. It is unit less
