When heated, KClO3 solid forms solid KCl and O2 gas. A sample of KClO3 is heated and 226 mL of gas with a pressure of 744 mmHg is collected over water, at 26 degrees C. At 26 degrees C, the vapor pressure of water is 25 mmHg: a) What is the pressure of the dry O2 gas? b) How many moles of O2 were produced? c) How many grams of KClO3 were produced
