Assuming ideal gas behavior, the ratio of density of ammonia to that of hydrogen chloride at same temperature and pressure is: (Atomic weight of Cl is 35.5 u)

Options

A $1.46$
B $1.64$
C $0.46$
D $0.64$

Correct answer

C. $0.46$

Step-by-step solution

d = \dfrac{P ( M . W . )}{RT}

\dfrac{{d}_{{NH}_{3}}}{{d}_{HCl}} = \dfrac{{( M . W . )}_{{NH}_{3}}}{{( M . W . )}_{HCl}} = \dfrac{17}{36 .5} = 0 .46
