Question

Two elements x atomic mass 16 and y atomic mass 14 combine to form compounds a,b and c

Answer 1

x and y are oxygen and nitrogen respectively

Answer 2

Answer: THE CORRECT ANSWER IS 70

Explanation:

SINCE, IN COMPOUND B

32 PARTS OF X COMBINE WITH 84 PARTS OF Y

⇒║SO, 16 PARTS WILL COMBINE WITH 42 PARTS

   AND ALSO WE ARE GIVEN THE RATIO 1:3:5

    HENCE, 3X=42

    X=14

IN C, WITH 16 PARTS OF X, 5X PARTS WILL COMBINE

5X=5 X 14 = 70
