The following questions apply to separation of a solution containing pentanol (FM 88.15) and 2,3-dimethyl-2-butanol (FM 102.17). Pentanol is the internal standard.

(a) Separation of a standard solution containing 213 mg of pentanol and 275 mg of 2,3-dimethyl-2-butanol in 10.0 mL of solution led to a pentanol:2,3-dimethyl-2-butanol relative peak area ratio of 0.917:1.00. Calculate the response factor, F, for 2,3-dimethyl-2-butanol.

(b) Calculate the areas for pentanol and 2,3-dimethyl-2-butanol gas chromatogram peaks in an unknown. For pentanol, the peak height was 31.9 mm and the width at half-height was 2.0 mm. For 2,3-dimethyl-2-butanol, the peak height was 47.0 mm and the width at half-height was 4.0 mm. Assume each peak to be a Gaussian.
