How many atoms are present in 4.2 moles of aluminium?

Answer 1

A mole is 6.022x1022. Therefore, 5.75x1024/6.022x1022 = 95.482323 moles (9.55 moles of Al).

Answer 2

Given:

4.7 mol Al

Known:

1 mol Al = 6.022 x 1023 atoms (Avogadro's number)

Calculations:

4.7 mol Al x (6.022 x 1023/1mol Al) = 2.8 x 1024 atoms Al

Answer 3

Avagadro's Number: 6x1023 molecules. That is how the Mole is defined. It does not matter what particles are involved. One Mole is a number just like One Dozen.

Answer 4

9.55 moles contain 5.75 x 1024 atoms of Al.

Answer 5

6.0 x 1023 atoms = 1 moleSo, 8.6 x 1022 atoms = 0.14 mole

Answer 6

The answer is: 4,2 x 6,02214129(27)×1023 = 25,292993418 x1023 atoms.

Answer 7

a. 9.55 mole of Al

Answer 8

It is about 0.7 moles or 18.82 g of Al.

Answer 9

Here are 7,6 moles.
