1.Determine the volume of oxygen produced by heating 250.0 grams of KClO3 at STP.

2 KClO3 → 3 O2 + 2 KCl

The molar mass for KClO3 is 122.6 g/mol.



2. A gas is at a pressure of 13 atm, a volume of 26 liters, and a temperature of 273 K. The pressure is raised to 16 atm and the temperature is increased to 320 K. What is the new volume of the gas?
