Question

Atoms of element y form hcp lattice and those of the

element x occupy 1
/3 rd of tetrahydral voids. What is the

formula of the compound formed by the elements x and y?

(A) X4Y3
(B) X3Y4
(C) X3Y2
(D) X2Y3​

Answer 1

Answer:

hey j think X3Y4.IF IT IS CORRECT THEN HIT ME AS BRAINLEIST OR YOU CAN FOLLOW

Answer 2

Answer:(B) X3Y4

Explanation:

Y from hcp Y = 6

Tetrahedral void = 2 ×6 = 12

For x, only 1/3 rd occupy,

= 1/3 rd × 12 = 4

So, x=4 and Y =12

X:Y = 3 : 4
