Question

Which of the following contains maximum number of molecules ? (A) 100 cc of CO2 at S.T.P (B) 150 cc of N2 at S.T.P (C) 50 cc of SO2 at S.T.P (D) 150 cc of O2 at S.T.P

Tardigrade Admin · Accepted Answer

Equal volume of all gases, under similar conditions of temperature and pressure contains equal number of molecules (Avagadro’s Law) ∴ 200 cc of NH3 at S.T.P. contains maximum number of molecules

Q. Which of the following contains maximum number of molecules ?

100 cc of $C O_{2}$ at S.T.P

150 cc of $N_{2}$ at S.T.P

50 cc of $S O_{2}$ at S.T.P

150 cc of $O_{2}$ at S.T.P

200 cc of $N H_{3}$ at S.T.P

Equal volume of all gases, under similar conditions of temperature and pressure contains equal number of molecules (Avagadro’s Law)
$∴ 200 cc$ of $N H_{3}$ at $S . T . P .$ contains maximum number of molecules
