Question

how many atoms are present in 320 amu of sulphur​

Answer 1

Answer:

first clearly right the question it would be 32 not 320

Explanation:

One mole of oxygen gas weighs 32 g at STP.

That means 32 amu of O2 will be equivalent to 1 mole.

1 mole of anything contains 6.023x10^23 particles.

So 1 mole of Oxygen gas contains 6.023x10^23 molecules.

Or by extention 1 mole of O2 gas contains 12.046x10^23 atoms of Oxygen.
