For a 35.83 g sample of potassium chlorate, the mass of potassium chloride is mathematically given as
M Kcl=21.62g
<h3>What is the mass of potassium chloride you expect to release upon heating?</h3>
Generally, the equation for the Chemical Reaction is mathematically given as
2KClO_3----->2KCl+2O_2
Therefore

Mole of KCl=0.29mol
Mass of Kcl=0.29*74.55
Mass of Kcl=21.62g
In conclusion, Mass of Kcl
M Kcl=21.62g
