Question

:]Calculate number of oxygen atoms in 66 g of carbon di oxide​

Answer 1

Answer:

24.08x1023

Explanation:

Answer 2

Answer: 18.07× 10^23

Explanation:Molar mass of Co2 - 12+16×2= 44gm.

44 gm of Co2 gives 1 Mol of Co2

66 gm of Co2 gives 1.5 Mol of Co2

Then , 1 Mol Co2 contain 2 Mol of O2

1.5 Mol of Co2 contain 3 Mol of O2

So, no of atom = no of Moles × avogrado's no

= 3 × 6.023×10^23

= 18.07 ×10^23
