Question

calculate the no of oxygen atoms in 1 mol of o2​

Answer 1

Answer:

No of Oxygen atoms in 1 mol of O2 = 6.022 × 1023 atoms

Answer 2

Answer:

12.046×10^23

Or

1.2046×10^24

Explanation:

Molecular mass of O2 is 32

1 mol of any substance has avogadro no. Of molecules

Here he hath asked us the no. Of atoms

So in this case we will multiply the avogadro's no. With the total no. Of atoms present for example oxygen O2 has two atoms of oxygen, N2 has two atoms of Nitrogen, h2o has two atoms of hydrogen and 1atom of oxygen etc.

Therefore, no. Of atoms of O2 will be 2 times the avogadro's no.

ie. 2×6.023×10^23 = 12.046×10^23

Or

1.2046×10^24 Ans
