Answer:
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
