Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Weights of atoms and isotopes are from NIST article.

It is a metal and ingestion will lead to CADMIUM POISONING. Lead: A soft, grayish metal with poisonous salts; atomic number 82, atomic weight 207.19, symbol

Lead is a soft, highly malleable and bluish-white lustrous metal with atomic no. 82. Understand the uses of lead, lead melting point, the density of lead and atomic mass.

2020-11-16 By scanning the periodic table, we find that Lead, denoted by {eq}\rm Pb{/eq}, has an atomic number of 82 and a molar mass of 207.2 grams per mole. Other articles where Lead-206 is discussed: dating: Model ages: For example, the ratio of lead of mass 206 relative to that of mass 204 has changed from an initial value of about 10 present when Earth was formed to an average value of about 19 in rocks at the terrestrial surface today. This is true because uranium is continuously… Some Conventions. The term "Average Atomic Weight" or simply "Atomic Weight" is commonly used to refer to what is properly called a "relative atomic mass".Atomic Weights are technically dimensionless, because they cannot be determined as absolute values.

A new very heavy atomic weight moderator is proposed—radiogenic lead consisting mainly of isotope 208Pb. It is characterized by extremely low neutron

The atomic mass unit (u) is defined as a mass equivalent to 1 / 12 of the mass of one atom of carbon-12. 1 u = 1.66 × 10-27 kg . We can estmate the the relative atomic mass (atomic weight) of an element E with the naturally occurring isotopes a E, b E, c E, etc, and with the respective abundances of A%, B%, C% etc,
