The element lead consists of four naturally occurring isotopes with atomic masses 203.97302, 205.97444, 206.97587, and 207.97663 . The relative abundances of these four isotopes are 1.4, 24.1, 22.1, and 52.4%, respectively.
relative atomic mass
The relative atomic mass of magnesium is approximately 24.305.
Approximately 4.01
Lead's atomic mass is 207.2 Its atomic number is 82
The chemical element with a relative atomic mass of 173 is Ytterbium (Yb).
The relative formula mass of lead oxide (PbO) is calculated by adding the atomic masses of the elements in the formula. The atomic mass of lead (Pb) is 207.2 g/mol, and the atomic mass of oxygen (O) is 16.0 g/mol. Therefore, the relative formula mass of lead oxide is 207.2 + 16.0 = 223.2 g/mol.
