Question

how The areas under the peaks on a gas chromatogram for a mixture of ethyl acetate and toluene were 85 "units" at 2.5 minutes elution and 30 "units" at 3.2 minutes respectively. What was the composition of the mixture

Answer 1

Answer:

74 % major, 26 % minor product  

Explanation:

The total area under the peaks is  

85 units + 30 units = 115 units

$\text{\% Major component} = \dfrac{\text{85 units}}{\text{115 units}} \times 100 \, \% = \mathbf{74 \, \%}\\\\\text{\% Minor component} = \dfrac{\text{30 units}}{\text{115 units}} \times 100 \, \% = \mathbf{26 \, \%}$
