Question

Which has more atoms: 10 g of Al or 10 g of Fe? Elaborate...

Answer 1

Answer:

Hi mate here's your answer.

Explanation:

1 mole of Al = 27g

10 g of Al = 0.37 mol = 0.37*6.023*10^23 atoms = 2.28 atoms

1 mole of Fe = 56g

10 g of Fe = 0.17 mol = 0.17*6.023*10^23 atoms = 1.02 atoms

Hope you get it.

Answer 2

Solution :-

Here we have

• 10 g Al

• 10 g Fe

Now we have to find out who have the highest number of atoms amongst these two given samples.

Now as we know number of atoms

= Moles × Avogadros Number

Now we also know

• Mass of one mole of Al = 27 g

• Mass of one mole of Fe = 56 g

Now clearly Moles of Al > Moles of Fe

→ 10 g Al have more atom than 10g Fe
