Calculate the volume of 10^23 molecules of oxygen at STP

1.	Calculate the volume of 10^23 molecules of oxygen at STP
Answer» ANSWER: volume at NTP occupied by 10^21 MOLECULES of Oxygen No. of moles = No. of molecules / N .... ( N is avagadro number....)... No. of moles = 10^21 / 6 × 10^23 ... = 1/6 × 10^-2 = 0.0016 ... Volume at STP = moles × 22.4 = 0.0016 × 22.4 = 0.037 L.

Answer»

volume at NTP occupied by 10^21 MOLECULES of Oxygen

No. of moles = No. of molecules / N .... ( N is avagadro number....)...

No. of moles = 10^21 / 6 × 10^23 ...

= 1/6 × 10^-2 = 0.0016 ...

Volume at STP = moles × 22.4

= 0.0016 × 22.4 = 0.037 L.
