Calculate the percentage composition of each element in Potassium chlorate KCIO3.
Calculate the percentage composition of Potassium chlorate KCIO3.
Advertisements
Solution
Molar mass of KCIO3 .
= 39 + 35.5 + 48 g
= 122.5 g
So, percentage of Potassium [K]
= `39/122.5 xx 100 %`
= 31.83 %
Now, Percentage of chlorine [Cl]
=`35.5/122.5 xx 100%`
= 28.97 %
Percentage of Oxygen [O2]
= `48/122.5 xx 100%`
= 39.18 %
