Two elements

X

and

Y

have atomic weights of 14 and 16. They form a serics of compounds

A, B, C, D

and

E

in which the same amount of element

{X},{Y}

is present in the ratio

1: 2: 3: 4: 5.

If the compound

A

has 28 parts by weight of

X

and 16 parts by weight of

{Y},

then the compound of

{C}

will have 28 parts weight of

{X}

and

View answer and explanation

Correct option: B

48 parts by weight of

{Y}

Option B (48 parts by weight of Y) is correct because if compound A is XY, then compound C (XY3) will have 28 parts by weight of X and 48 parts by weight of Y.
