n a gas chromatography experiment, the response factor between an alcohol and an alkane, serving as an internal standard, had a response factor of 2.54. The alkane internal standard had a concentration of 25.9 nM and a peak area of 92832. The peak area for the alcohol was found to be 23422. What is the concentration (in nM) of alcohol in the sample
