Mass of KCl : 32 g

Further explanation

Given

Reaction

2KCIO₃ → 2KCI + 30₂

52 g Potassium chlorate

Required

Mass of KCl

Solution

mol of KCIO₃ :

= mass : MW

= 52 g : 122.55 g/mol

= 0.424

From equation, mol KCl :

= 2/2 x mol KCIO₃

= 2/2 x 0.424

= 0.424

Mass KCl :

= mol x MW

= 0.424 x 74.5513 g/mol

= 31.6≈32 g
