- The atomic mass of lithium is: (0.0750)(6.015121) + (0.9250)(7.016003) = 6.94 u. Recall that the atomic mass is a weighted average of all isotopes of an element, and is obtained by adding the product of (relative abundance x mass) for all isotopes. 13. The two stable isotopes of silver are Ag-107 and Ag-109. The masses of the isotopes are. respectively: 106.9051 and 108.9047.

What is Rhodium â Properties of Rhodium Element â Symbol Rh Atomic Mass of Rhodium. Atomic mass of Rhodium is 102.9055 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10-24 grams. One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol.

Silver The atomic weight is 107.8682(2) u; this value is very important because of the importance of silver compounds, particularly halides, in gravimetric analysis. Both isotopes of silver are produced in stars via the s-process (slow neutron capture), as well as in supernovas via the r-process (rapid neutron capture).

CONTENTS The average atomic mass of neon is thus: The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams.

Atomic mass From Wikipedia, the free encyclopedia. An atomic mass (symbol: m a) is the mass of a single atom of a chemical element. It includes the masses of the 3 subatomic particles that make up an atom: protons, neutrons and electrons. Atomic mass can be expressed in grams. However, because individual atoms have very small masses, this is not very helpful.
