Question

calculate the number of atoms in 48g of oxygen​

Answer 1

Now u have 48 g of O2. There. Fore mole=weight/M. W. Of oxygen. Therefor 3mole.

Now u have 48 g of O2. There. Fore mole=weight/M. W. Of oxygen. Therefor 3mole.After that if we to multiply the avogadro number with it. So 3 *NA

Now u have 48 g of O2. There. Fore mole=weight/M. W. Of oxygen. Therefor 3mole.After that if we to multiply the avogadro number with it. So 3 *NANow u want only atom calculation then we have 2 molecule of oxygen then multiply it with 2 too.

Answer 2

Answer:

9.033 ˣ $10^{23}$ atoms.

Explanation:

No. of moles = 48/32=1.5

No of atoms= 6.022 ˣ $10^{23}$ ˣ  1.5 = 9.033 ˣ $10^{23}$ atoms.
