Question

Calculate the no. of molecules in 5.6 litres of oxygen at S.T.P.

Answer 1

We know that 22.4litres of oxygen at STP contain 6.02×1023 molecules of oxygen.

So,5.6litres of oxygen at NTP contain=5.622.4×6.02×1023 molecules.

⇒1.505×1023 molecules.

Answer 2

1.505×1023 molecules are available
