| In an experiment, 2 g of Nitrogen gas reacts with 6 g of Hydrogen to form 8 g of Ammonia. Then when 2 g of Nitrogen reacts with 12 g of Hydrogen, what mass of Ammonia will be produced?
A.
14 gm
B.
10 gm
C.
8 gm
D.
7 gm

Right Answer is: C
SOLUTION
According to the law of constant proportions:
Since, Nitrogen and Hydrogen combine in the fixed proportion of 2:6 by mass to produce 8 g of Ammonia, therefore in second case also, 2g of Nitrogen will combine with 6g of Hydrogen (2:6 mass ratio) and not 12g. Hence, the same mass of Ammonia will be produced.
