the formula: Ca(ClO3)2 --> CaCl2 + 3O2
what mass pf O2 results from the decomposition of 1.00 kg of calcium carbonate
Convert kg to g.
Convert g Ca(ClO3)2 to moles. moles = g/molar mass.
Using the coefficients in the balanced question, convert moles Ca(ClO3)2 to moles O2.
Convert moles O2 to grams. grams = moles x molar mass. Post your work if you get stuck.
