Assuming ideal gas behaviour, the ratio of density of ammonia to that

1.	Assuming ideal gas behaviour, the ratio of density of ammonia to that of hydrogen chloride at same temperature and pressure is ………….. (Atomic wt. of Cl = 35.5 u) (A) 1.46 (B) 0.46 (C) 1.64 (D) 0.64
Answer» Correct option is: (B) 0.46 PM = \(\rho\)RT At same temperature and pressure \(\frac {PM_{NH3}}{PM_{HCl}} = \frac {\rho_{NH3}RT}{\rho_{HCl}RT}\) = \(\frac {\rho_{NH3}}{\rho_{HCl}} = \frac {17}{36.5} \) = \(\frac {\rho_{NH3}}{\rho_{HCl}} \) = 0.46 Correct option is (B) 0.46

Answer»

Correct option is: (B) 0.46

PM = \(\rho\)RT

At same temperature and pressure

\(\frac {PM_{NH3}}{PM_{HCl}} = \frac {\rho_{NH3}RT}{\rho_{HCl}RT}\)

= \(\frac {\rho_{NH3}}{\rho_{HCl}} = \frac {17}{36.5} \)

= \(\frac {\rho_{NH3}}{\rho_{HCl}} \)

= 0.46

Correct option is (B) 0.46
