A mole of PbCl2 has 1 mol of lead atoms and 2 mol of chlorine atoms. You find the molar mass of the compound by adding these molar masses together; 207.2 + 2

Lead (Pb) Atomic Data for Lead (Pb) Atomic Number = 82 Atomic Weight = 207.2 Reference E95 : Isotope : Mass : Abundance : Spin : Mag Moment : 204 Pb:

14452-81-4. Lead Lead (Pb) Atomic Data for Lead (Pb) Atomic Number = 82 Atomic Weight = 207.2 Reference E95 207.976 652 (8) 0.524 (70) The atomic weight of lead is quite variable in nature because the Atomic mass of Lead is 207.2 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. ››More information on molar mass and molecular weight.

Lead's close-packed face-centered cubic structure and high atomic weight result in a density of 11.34 g/cm 3, which is greater than that of common metals such as iron (7.87 g/cm 3), copper (8.93 g/cm 3), and zinc (7.14 g/cm 3). This density is the origin of the idiom to go over like a lead balloon.

particle size 150 micron, weight 2000 g, purity 99.5%. Lead atomic spectroscopy standard concentrate 1.00 g Pb, 1.00 g/L, for 1L standard solution, analytical standard. Lead atomic spectroscopy standard concentrate 10.00 g Pb, 10.00 g/L, 2020-08-19 Lead has been known since ancient times. It is sometimes found free in nature, but is usually obtained from the ores galena (PbS), anglesite (PbSO 4), cerussite (PbCO 3) and minum (Pb 3 O 4).Although lead makes up only about 0.0013% of the earth's crust, it is not considered to be a rare element since it is easily mined and refined. Thus the atomic weight of lead is 207.2 g/mol, as mentioned earlier in the discussion.
