Lead is soft and considered a poor metal, which means that it is a metallic element in the p-block. 20. The mass of one mole of lead (Pb) atoms is 207.2 g. Use a proportion to calculate the n lead atoms in a 15.00 g sample of lead. 2. Y i n the mathematical relationship between atomic mass units (amu) and grams (g) ?

As we know, in the past, all the plumbing was made of lead, which results in poisoning and death. Thankfully, it no longer is. Lead is soft and considered a poor metal, which means that it is a metallic element in the p-block. 20. The mass of one mole of lead (Pb) atoms is 207.2 g.
