One mole of lead weighs 207.2 grams, approximately how many atoms of lead are in one mole of lead? a
3.404 *10^21
b
3.404 * 10^23
c
6.022*10^23
d
6.022 *10^21

c. 6.022*10^23 atoms

Explanation:

According to this question, one mole of Lead (Pb) contains 207.2g. This means that the molar mass of lead is 207.2g/mol.

That is, since mole = mass ÷ molar mass

Molar mass = mass ÷ mole

Molar mass = 207.2g ÷ 1 mole

Molar mass = 207.2g/mol

Based on Avogadro's principle;

1 mole of an element = 6.022 × 10^23 atoms

Hence, one mole of lead will contain 6.022× 10^23 atoms

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
