Explanation / Answer

From the given chromatograms

UNK-0007 KOH 4

Total area of products = 957464 + 1211257 = 2168721

% of 2-methyl-1-butene = 44.15%

% of 2-methyl-2-butene = 55.85%

Ratio (2-methyl-1-butene : 2-methyl-2-butene) = 1 : 1.265

UNK-0009 tBuOH 2

Total area of products = 462524 + 474022 = 936546

% of 2-methyl-1-butene = 49.39%

% of 2-methyl-2-butene = 50.61%

Ratio (2-methyl-1-butene : 2-methyl-2-butene) = 1 : 1.025
