Given that the mass of the proton is 
and that
the mass of an electron is 
...
- a.
- How many significant figures are there in the given proton mass?
The electron mass?
- b.
- Express the mass of the Hydrogen atom (one proton and one electron)
with the correct number of significant figures.
(Note: We are neglecting the binding mass... If you don't understand what that
is, first, realize that you don't really need to know this to solve this
problem, and second, ask your professor to explain what the binding mass is...)
