Options:
A) 100 ml
B) 20 ml
C) 40 ml
D) 60 ml
Show Answer
Answer:
Correct Answer: B
Solution:
$ \underset{\underset{t=t}{\mathop{t=0}}\underset{0}{\mathop{20ml}}\underset{20,ml}{\mathop{40ml}}\underset{solid}{\mathop{0}},}{\mathop{N{H _{3(g)}}+HC{l _{(g)}}\to NH _4C{l _{(s)}}}}, $
Final volume = 20ml.
