Q. A cylinder contains $68g$ of ammonia gas at s.t.p.
What is the volume occupied by this gas?

Q. When ammonia reacts with hydrogen chloride gas, it produces white fumes of ammonium chloride. The volume occupied by $N{H}_3$ in glass bulb $A$ is three times more than the volume occupied by $HCl$ in glass bulb $B$ at STP.
i) How many moles of ammonia are present in glass bulb $A$?
ii) How many grams of $N{H}_{3}Cl$ will be formed when the stopper is opened?
(Atomic mass of $N=14,H=1,Cl=35.5)$
iii) Which gas will remain after completion of the reaction?
iv) Write the chemical reaction involved in this process.

Q. If a gas occupies 22400 L of volume at STP, how many moles of the gas are present?
