Answer 1

Answer:

10gm of iron

Explanation:

from my view it's iron Becoz it's 10gm

pls correct me if I am wrong

Answer 2

1 mole of Aluminium has a mass of 27 grams and has 6.023 x 10^23 atoms.

1 mole of iron has a mass of 56 grams and has 6.023 x 10^23 atoms of iron.

So, 10 grams of Al is 10/27 moles => 0.37 moles.

So, 10 grams of Fe is 10/56 =>0.178 moles.

=> As we know, larger the number of moles, more the number of atoms.

So, 0.37 moles of Al has more atoms than 0.178 moles of Fe.

Hence, 10 grams of Aluminium has more number of atoms than 10 grams of iron.
