Question:-
Find the volume of oxygen that reacts with 1.12 L of NH3.
Equation:-

Options :-
0 0.896 L
O 1.4L
0 1.12
0 561
Answer:- 1.4L
Given:-
- 4 moles of NH3 reacts with 5 moles of O2 to produce 4 moles of NO and 6 moles of H2O .
- 1.12 L is the amount of NO which have to react with O2
To find :- amount of O2 with will react with 1.12 L of NH3
Explanation:-
Formulas:-
- Conservation of mass

According to the reaction:-

4 moles of NH3 reacts with 5 moles of O2
so:-
1 mole of NH3 reacts with 5/4 moles of O2
Number of moles given of NH3 :-

For given moles :-

So numbers of moles of O2 required:-

To convert it into volume of gas in lts just multiple it with 22.4 lts :-

Option :- Second :- 1.4 L
