What mass of KCl in grams is formed when 2.00 lbs of KC103 is decomposed?
KClO3 --> KCl + O2
Balanced the equation.
2KClO3 ==> 3O2 + 2KCl
Convert lbs KClO3 to grams. There are 453.6 grams/lb.
mols KClO3 = grams/molar mass
Using the coefficients in the balanced equation, convert mols KClO3 to mols KCl.
Now convert mols KCl to grams. g = mopls x molar mass.
