Question

Which of the following is a wrong Combination?
I. 6.022 * 1023 molecules of oxygen = 32g of oxygen II. 6.022 * 1023 ions of sodium = 23g of sodium III. 6.022 * 1023atoms of C = 24g of carbon IV. 6.022 * 1023 atoms of H = 1g of hydrogen atoms

Answer 1

Answer:

As both, O

2

and S have same mass so 32 g of O

2

contains same number of moles as 32 g of S.

So, they both have same number of molecules at NTP.

Therefore, 32 g of S contains 6.022×10

23

atoms.
