Answer 1

1. The peak area of ethyl acetate = {87500/(87500+97500)}*100 = 47.3%

Now, the peak area of butyl acetate = 100 - 47.3 = 52.7%

2. The peak area of ethyl acetate = {190000/(42500+190000)}*100 = 81.7%

Now, the peak area of butyl acetate = 100 - 81.7 = 18.3%

3. The peak area of ethyl acetate = {205000/(17500+205000)}*100 = 92.1%

Now, the peak area of butyl acetate = 100 - 92.1 = 7.9%
