Question

How many atoms of aluminum (Al) are in 2.15 mol of aluminum? answer in units of atoms.

Answer 1

Answer:
`1.295x10^2^4atoms`

Step-by-step explanation:

Using avogadro's number;

`2.15molAl((6.022x10^2^3atoms)/(1molAl))= 1.295x10^2^4atoms`

Answer 2

This means that the mass of one mole of aluminium atoms will be 26.982 g . As you know, one mole of any element contains exactly 6.022⋅1023 atoms of that element.
