Unformatted text preview: 3. (24 points) A known 1:1 mixture of A and B (by volume) is analyzed by GC. The relative peak areas are recorded. 10.-mL of an unknown mixture is analyzed by
GC by injecting 1 microliter of the mixture. The resulting peak areas are recorded.
Based on these numbers, determine the relative response factors and the total
volume of A and B in the unknown mixture. (Be sure to pay attention to
signiﬁcant ﬁgures!). For standard 1:1 (by volume) mixture of A+B: For 1 microliter of unknown: area 121.11.!
