Question

What gm of kcl obtained when 10 gm kclo3 is heated

Answer 1

2kclo3 ------> 2kcl + 3O2


So 2 moles of kclo3 have 245g
And 2 moles of kcl have 149g
245g of kclo3 gives 149 g of kcl
So 1 g gives 149 ÷ 245 g of kcl
And 10 g gives 149 × 10 ÷ 245g of kcl
Kcl = 6.08 gram



Hope it's help full....
