Question

Which has more atoms 50g of Aluminium or 50g of Fe ? Illustrate you answer .

Answer 1

Answer:

aluminum have more atoms.

Explanation:

Atomic masses: Al = 27 u; Fe = 56 u) Thus, 50g of Al has more no. of atoms as compared to 50g of Fe. This is because Aluminium has a smaller atomic mass and is lighter.

Answer 2

Answer:

Aluminum.

Explanation:

because 50g of aluminium contains 1.85 moles of aluminium and it's known that 1 mole of every substance contains 6.022×10^23 atoms so 50g aluminium will contain 1.85×6.022×10^23= 1.11×10^24 atoms

while,

50g of Fe contains 0.89 moles of Fe and thus will contain 0.89×6.022×10^23= 5.35×10^23 atoms.
