You have obtained a gas chromatogram of a two component mixture of compounds A and B. The height of peak A is 3.33 cm. and the width at half height is 1.61 cm. The height of peak B is 3.97 cm. and the width at half height is 1.11 cm. The percentage of a component in the mixture is proportional to peak area. Estimate peak areas by multiplying height by width at half height. What was the percentage of compound...

A mixture of two compounds (A and B) was separated by gas chromatography on a non-polar column. The chromatogram was recorded on a chart recorder that fed paper at a constant speed of 100 mm per minute, and a mark was made on the chart when the sample was injected. The first peak on the chromatogram corresponds to compound A, and that peak was observed at a distance of 5.42 cm from the sample injection point, and it had a...

A student was able to separate the three components of a mixture via liquid chromatography. She obtained 1.33 g of component A, 0.970 g of component B, and 0.350 g of component C. Determine the mass percent of each of the three components in the mixture. mass percent of A= mass percent of B = mass percent of C =
