If excess water is added into 1.0 gm sample labelled as "112% oleum" and is reacted with $1.06 gm Na_{2} CO_{3}$ , the find the volume of $CO_{2}$ evolved at 1 atm and 300 K temperature after completion of the reaction.

Answer:

Solution:

$1.06 gm Na_{2} CO_{3}$ means 0.01 mole $Na_{2} CO_{3}$

$Na_{2} CO_{3} + H_{2} SO_{4} \to Na_{2} SO_{4} + H_{2} O + CO_{2}$

0.01 mole

$n_{CO_{2}} = 0.01$ mole

$PV = nRT$

$1 \times V = 0.01 \times 0.821 \times 300$

$V = 0.2463$ litre.
