What mass of KCl in grams is formed when 2.00 lbs of KC103 is decomposed?

KClO3 --> KCl + O2

  • chem -

    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.
