Warm Up 3/6/17
2KClO3à2KCl + 3O2
Volume of O2 collected over water.....350.0mL
Atmospheric pressure....................750.0mmHg
Temperature of water...................18.0oC
Vapor pressure of H2O at 18.OoC......15.8mmHg
1) Calculate the number of moles of oxygen collected
(actual yield)
2) If 1.31g of KClO3 decomposed, how many moles of
oxygen should have been produced. (theoretical yield)
3) Calculate the percent error.
