Questions

Calculate the percentage composition of each element in Potassium chlorate KCIO3.

Calculate the percentage composition of Potassium chlorate KCIO3.

Numerical

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 %
