MolSynapse / Question bank / Gaseous State: Ideal Gases / Density and molar mass of gases

JEE Main levelSingle correct optionDifficulty 2 of 3ig078

At the same temperature and pressure, the ratio of the densities of $SO X_{2}$ (64) and $CH X_{4}$ (16) is

A $4 : 1$
B $2 : 1$
C $1 : 4$
D $16 : 1$

Answer: A

d = PM / RT

, so at equal

T

and

P

,

d_{SO X_{2}} / d_{CH X_{4}} = M_{SO X_{2}} / M_{CH X_{4}} = 64/16 = 4

.
