Question

Assume that you have 2.59 mol of aluminum. How many atoms of aluminum do you have?

Answer 1

Answer:

1.559*10^24 atoms

Explanation:

This is based on mole concept

one mole of element/compound = avogadro number of atoms = Atomic mass of atom

Avogadro number = 6.022*10^23

one mole of of Aluminium have 6.022*10^23 of atom

then 2.59 mol of Aluminium will have 2.59*6.022*10^23

= 1.559*10^24

Answer 2

Answer:

2.59 mol of aluminum contains 15.59x10²³ atoms

Explanation:

Given 2.59 moles of Aluminium.

So atomic mass of Aluminum is 27u

Molar mass of Al is 27g which is one mole which contains 6.022x10²³ atoms

So 1 mole of Al that is 27g contains 6.022x10²³ atoms

1 mole ---->6.022x10²³ atoms

2.59 moles ---->?

= 2.59 x 6.022 x 10²³

=15.59x10²³ atoms
