7.000 g sample of solid potassium chlorate is decomposed in the presence of the catalyst MnO2 to yield solid potassium chloride and oxygen gas. (MnO2 is written above the arrow of the chemical equation and is NOT used in any of the calculations. Remember, catalysts are not consumed by a chemical reaction; they only speed it up.) The oxygen gas is collected and stored in a 5.00 L gas tank at a temperature of 19.00oC. What is the pressure inside the tank?
