. Suppose 2.6 g of hexane is mixed with 13.3 g of oxygen. Calculate the minimum mass of hexane that could be left over by the
Given: 2.6 g of hexane is mixed with 13.3 g of oxygen
To find: Minimum amount of oxygen left after completion of the reaction ( By mistake you have written hexane but hexane is a limiting reagent and oxygen is a reagent which is in excess)
Solution: Limiting reagent are those reagents which are consumed completely first.
Exces reagent are those which are left even after the completion of the whole reaction.
