Question

How many mols in 2.25x10^25 atoms of Zinc

Answer 1

37.4 mol.

Step-by-step explanation:

Hello!

In this case, since the Avogadro's number help us to realize that one mole of any substance contains 6.022x10²³ formula units, in this case atoms of zinc, the following dimensional analysis provides the correct answer:

`=2.25x10^(25) atoms*(1mol)/(6.022x10^(23)atoms)\\\\= 37.4mol`

Best regards!
