2. Several standards were chromatographed, 0.5 1.0 2.0 Conc (ug/ml) Peak area 5.0 10.1 17.2 and the results are shown below: 3.0 6.0 8.0 19.8 39.7 57.3 10.0 66.9 15.0 95.3 Graph using concentration as the X-axis and peak area as the Y-axis. Use Excel to determine the equation of the line. What type of standardization was used above?

please help me find average and standard deviation
I have set up my spreadsheet and was able to reproduce the result with a pKa of 4.64. TRUE OR FALSE
What is the relative average deviation in the following percent KHP values in ppt? 46.80% 47.23% 48.03%
How would you calculate Standard Deviation?
QUESTION 5 In a chromatographic separation using a polar stationary phase and a mobile phase composed of 60% hexane and 40% ethyl acetate, two compounds, benzene (peak A) and toluene (peak B), are eluted. The width of peak A at its base is 1.2 min, the width of peak B at its base is 1.3 min, and the retention time of peak A is 5.2 min and peak B is 3.5 min. What is the resolution (Rs) between these two peaks and is it acceptable? R = 1.36. It is not an acceptable resolution. R = 0.74. It is an acceptable resolution. R = 1.36. It is an acceptable resolution. R = 0.74. It is not an acceptable resolution.
Which is correct? Random errors affect accuracy and systematic errors affect precision. An accurate result shows agreement with the true or accepted value. Precise results can contain significant random error, but little systematic error. The standard deviation is a good measure of accuracy. Polydimethylsiloxane (PDMS) stationary phases have low polarities. Which of the following statements is TRUE about gas chromatography using PDMS stationary phases? The gas chromatography column is typically packed with silica microparticles. An oven is used to control the column temperature because a constant temperature is always needed in gas chromatography Octane (C8H18, boiling point: 126 ºC) is eluted later than dodecane (C12H26, boiling point: 216 ºC) 3-Pentanone ((C2H5)2CO, boiling point: 102 ºC) is eluted later than propanol (CH3CH2CH2OH, boiling point: 97 ºC)
1. As shown below, a student obtains two quality chromatograms for her distillate and pot samples, containing methanol and cyclohexanol. Match Chromatograms A and B with distillate or pot, and explain your conclusion. Circle your response: Chromatogram A A: Distillate or Pot Explain your answer: t=0 Chromatogram B B: Distillate or Pot
