MolSynapse / Question bank / Gaseous State: Ideal Gases / Eudiometry

JEE Main levelSingle correct optionDifficulty 2 of 3ig126

$40 mL$ of a mixture of $H X_{2}$ and $O X_{2}$ was sparked. After cooling, $10 mL$ of $O X_{2}$ remained. The volume of $H X_{2}$ in the original mixture was

A $20 mL$
B $30 mL$
C $10 mL$
D $25 mL$

Answer: A

Let

H X_{2} = a

,

O X_{2} = 40 - a

.

2 H X_{2} + O X_{2} 2 H X_{2} O (l)

uses

a /2

of

O X_{2}

. Remaining:

40 - a - a /2 = 10

, so

1.5 a = 30

,

a = 20 mL

.
