Question

identify which contains more number of atoms 12 gram carbon or 23 gram sodium​

Answer 1

Answer: Both contain the same number of atoms

Explanation: Atomic mass of carbon is 12

So, 12 g Carbon will have

No. of moles = given mass / molar mass = 12 / 12 = 1 mole

And atomic mass of sodium is 23

So, 23 g Sodium will have

23/23 = 1 mole

Now since there are 1 mole atoms in both the cases, they will have the same number of atoms.

Thus, this is the answer.
