Calculate the percentage composition of each element in Potassium chlorate, $K C l O_{3}$

Open in App

Solution

Molar Mass of $K C l O_{3}$
= $39 + 35.5 + 48 g$
= $122.5 g$ .

So , percentage of Potassium ( K )
= $\frac{39}{122.5}$ $\times 100$
= 31.83 %

Now , percentage of Chlorine ( Cl )
= $35.5 / 122.5 \times 100$
= 28.97 %

So, finally, percentage of Oxygen ( O )
= $48 / 122.5 \times 100$
= 39.18 %
