Consider the following balanced chemical reaction.
3A+4B+5C=2D
If 7 moles of A, 9 moles of B and 8 moles of C are given initially, what would be the mole fraction of D present after completion of reaction?

Answer: .4 is the right answer
Step-by-step explanation:
0.4mol is the answer.
explanation:
(i)
[tex]5 mol ------------- > 2\\8mol------------- > ?[/tex]
∴ [tex]D=3.2mol[/tex]
(ii)
[tex]4molB--------- > 5molCrequire\\ ? < -----------8molC[/tex]
[tex]6.4mol[/tex] [tex]used[/tex] [tex]left = 2.6mol[/tex]
(iii)
[tex]3molA------- > 5molC[/tex]
[tex]? < ----------8molC[/tex]
[tex]4.9 mol[/tex] [tex]used[/tex] [tex]left=2.2mol[/tex]
[tex]=\frac{3.2}{8}[/tex]
[tex]= 0.4[/tex]
