Answer:
Relative molecular mass of KClO
3
=39.09+35.5+(3×16)
=122.59g
122.59gKClO
3
contains 39.09gK
Hence, 100gKClO
3
contains
=
122.59
100×39.09
=31.9g
122.59gKClO
3
contains 35.5gCl
Hence, 100gKClO
3
contains
=
122.59
100×35.5
=28.9g
122.59gKClO
3
contains 48gO
Hence, 100gKClO
3
contains
=
122.59
100×48
=39.1g
The percentage of K,Cl and O in KClO
3
are 31.9%,28.9% and 39.1% respectively.

Answer:
31.83
Explanation:
Potassium chlorate is KClO3
% of atom X in KClO3=Molecular weight of KClO3(number of X atoms)×(Atomic weight of X)×100
For X=K, % K=122.51×39×100=31.83%
