Two elements X and Y have atomic masses 14 and 16 respectively. They can form a series of five compounds A, B, C, D and E in which for the same amount of X, Y is present in the ratio of 1:2:3:4:5. If the compound A has 28 parts by weight of X and 16 parts by weight of Y, then compound C will have 24 parts by weight of Y combined with

Options

A. 28 parts by weight of X
B. 14 parts by weight of X
C. 8 parts by weight of X
D. 4.1 parts by weight of X

Answer

B

Explanation

Ratio of X and Y in compound A is 1:1:
Ratio of X and Y in compound C is 1:3
Now if in compound A, 28 parts by wt. of X combine with 16 parts by wt. of Y then in compound C, 28 parts of X will combine with `16 xx 3 = 48 ` parts of Y
` therefore ` 24 parts of Y will combine with 14 parts of X in compound C .
