Answer 1

Answer:

Answer:

: Calculate the number of atoms of each element in 245 g of KCIO3.

Solution:

Molecular mass of KCIO3= 39+35.5+3x16=122.5

No. of mole of KCIO3= 245 g/122.5g = 2 mole =

2 mole of KCIO3contains

85%

2 mole of K = 2x6.022x1023=12.044x1023 K

atoms

2 mole of CI = 2x6.022x1023=12.044x1023 CI

atoms

6 mole of O = 6x6.022x1023=36.132x1023 O atoms.
