The provided question is incomplete, however, the complete question is attached with answer:
Answer:
The correct answer is : option A. Beakers A and B contain an equal number of atoms.
Step-by-step explanation:
No matter what is the element or substance, in one mole of any elemnet r metal or anything have 6.022×1023 everythings. So, beaker A have one mole of iron Fe and beaker B have one mole of Lead Pb, then the total atoms in each beaker will be equal that is :
1 mole of Fe = 1× 6.022×1023 atoms/mol
1 mole of Pb = 1× 6.022×1023 atoms/mol
Thus, the correct answer is: option A. Beakers A and B contain an equal number of atoms.
