WebDec 24, 2015 · It would appear that Science Buddies intends for a relative salt concentration to be the amount of salt in any given cup out of the given cup's total amount of matter. This is essentially the percent of salt in the solution. As an example, they give a cup with a half-salt, half-water solution. They state that this is a 50% relative salt ... WebThe relative abundance of Deutrium (1 proton, 1 neutron) is so small that it is barely accounted for when calculating the average atomic mass. So the mass of a proton is around 1.008 amu, not 1. Following this logic, the carbon-12 atom's atomic mass should actually be 12.09 amu; however, the mass is exactly 12 amu. Why?
