8 0

Answer:

= 3.01 x 10²³ atoms of gold (Au)

Explanation:

1 mole of any substance => 1 Avogadro's Number of particles = 6.02 x 10²³ particles.

∴ for 5 moles of gold atoms => 5 moles x 6.02 x 10²³ atoms/mole

= 3.01 x 10²³ atoms of gold (Au)

Predict the shape of the molecule.
GuDViN [60]

Number of electron pairs = \frac{1}{2}[V+N-C+A]

2

1

[V+N−C+A]

V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

SbCl_5SbCl

5

:

In the given molecule, antimony is the central atom and there are five chlorine as monovalent atoms.

The number of electron pairs are 5 that means the hybridization will be sp^3dsp

3

B and geometry of the molecule will be trigonal bipyramidal.
