The Percent by Mass Octane Is Quantified for an Organic

question 6

Short Answer

The percent by mass octane is quantified for an organic sample via GC using decane as the internal standard.A GC vial containing 0.5023 grams organic sample and 0.2384 grams octane is prepared and analyzed,returning peak areas of 119,993 for octane and 83755 for decane.If a response factor of 2.50 from previous work analyzing octane with a decane internal standard is used,what is the percent by mass octane in the organic sample?
