Homework Help: Chemistry-please help

Posted by janice on Tuesday, January 20, 2009 at 2:28pm.

The relative mass of a proton is 1 and the relative mass of a neutron is 1. 1)Why do we use the term "relative mass" instead of mass? Is it because the mass of a proton is compared to the mass of a carbon-12 atom?
2) Can we say that the relative mass of an atom is 2 (proton+neutron)?
3) Is "relative mass" the same as "relative atomic mass"?

Please urgently help. Thanks.
