250. When determining furfural in a mixture by gas chromatography, the area of its peak Sfurfural was compared with the peak area of o-xylene Sxylene, which was introduced as a standard. For a standard sample containing 25% furfural and the test sample, the following results were obtained:
Option Standard sample Test sample
Sfurfural, mm2 Sxylene, mm2 Sfurfural, mm2 Sxylene, mm2
250 13 29 19.3 26
Take k equal to one for both components. Determine the percentage of furfural in the test sample.
