Answer 1

HEY__________________ MATE




ANSWER


Number of Y atoms in the given unit cell= 8*1/8=1

Number of X atoms in the given unit cell=1*1=1

Therefore formula of compound= X1:Y1=XY

Answer 2

hey

,.....
HERE IS YOUR ANSWER

Thus, number of atoms Y per unit cell

= Number of atoms × Contribution per unit cell

= 8 (at the corners) × 1÷8atoms per unit cell

= 1

Thus, number of atoms X per unit cell

= Number of atoms × 1÷8contribution per unit cell

= 1 (at the body centre) × 1

= 1

Thus, the formula of the given compound is XY.
