WebOct 25, 2013 · Relative Atomic Mass, Ar = [(2 X 185) + ( 3 X 187)] / (2 + 3) = 186 (3 sig fig) If the information given is in terms of % Abundance, the strategy to solve it is the same – just take the denominator to be 100 since % must add up to 100%. The best way to learn is to take actions and work on it yourself. 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? WebSince the real relative abundance of each isotope on earth is obtained via carrying a number samples around the world and analyzing their mass spectrum. Does this mean that the average atomic mass can be calculated and the element known after the examination of all those samples? • ( 1 vote) Upvote Downvote Flag Richard 2 years ago bits in ethernet address
