Answer 1

Answer:

your answer dear.........

Answer 2

Step-by-step explanation:

A number of an atom of an element in the compound = number of mole of the element in compound x Avogadro's number.

For KClO

3

, the number of moles of K, Cl. and O are 1, 1, and 3 respectively.

Thus,

Number of atoms of 'K' =1×6.023×10

23

Number of atoms of 'Cl' =1×6.023×10

23

Number of atoms of 'O' =3×6.023×10

23
