Some Basic Concepts Of Chemistry Question 58
Question: When burnt in air, 14.0 g mixture of carbon and sulphur gives a mixture of $ ~CO _2 $ and $ SO _2 $ in the volume ratio of 2:1, volume being measured at the same conditions of temperature and pressure moles of carbon in the mixture is
Options:
A) 0.75
B) 0.5
C) 0.40
D) 0.25
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Let weight of C be xg, then S will be $ ( 14-x )g $ $ \frac{x/12}{( 14-x )/32}=\frac{2}{1} $
$ \therefore x=6g $ ; Moles of $ C=\frac{6}{12}=0.5 $
