Pressurized metal gas cylinders are generally used to store commonly used gases in the laboratory.At times, it can be easier to chemically prepare occasionally used gases..For example, oxygen gas can be prepared by heating KMnO₄(s)according to the following chemical reaction:
2KMnO₄(s) $\rarr$ K₂MnO₄(s)+ MnO₂(s)+ O₂(g)
How many grams of KMnO₄ would you need to produce 0.27 moles of O₂, assuming 100% conversion? The molar mass of KMnO₄ is 158.034 g/mol.
