Final answer:
To establish the octane values of 89 and 93, different mixtures of 2,2,4-trimethylpentane and n-hexane are used. A fuel with a higher octane rating would contain more 2,2,4-trimethylpentane, which has a 100 octane rating, compared to n-hexane, which has an octane rating of 25.
Step-by-step explanation:
The exact mixture of 2,2,4-trimethylpentane and n-hexane required to establish the octane values of 89 and 93 can vary. These values represent the octane rating, which is a standard measure of the performance of an engine or aviation fuel. The higher the octane number, the more compression the fuel can withstand before detonating. In general, high-performance fuels are made with a greater proportion of 2,2,4-trimethylpentane, given its octane rating of 100, while n-hexane has an octane rating of about 25.
Consequently, a fuel with an octane rating of 89 would have a higher proportion of n-hexane compared to a fuel with 93 octane rating. To establish precise proportions, you would need additional information such as the specific process used to blend the fuels.
