Step by step
Solved in 2 steps
- The replicate results (mg/L) obtained from calcium determination of a blood sample using atomic absorption spectrophotometry (AAS) and a new colorimetric method were as following: AAS : 11.2, 11.2, 10.6, 11.2, 9.7 and 10.0 Colorimetric : 9.2, 10.5, 9.7, 11.5, 11.6, 9.3, 10.1 and 11.2 Determine whether the mean of both methods have a significant difference at 95% confidence level.What are the x and y values that you have input in the excel? I thought the x would be from the concentation and the y is from the A595 of sample minus A595 of blank but the linear equation that shows up in mine is different. It's y = 0.0443x + 0.0148.Is organism 1 a plant animal or neither explain what procedure would you used to perform test A then explain how the results of test A allow you to determine wether the test was positive or negative for organism 1?
- With reference to this data what is the number of samples (n)?The exact same information is learned when one does a Kirby Bauer test or an Epsilometer test (E-test). Select one:TrueFalseYou have carried out an experiment using the spectrophotometry concept. A solutioncontaining compound X is mixed with reagent 1 and then reagent 2. This mixture produces ablue colour whose absorbance (A) could be read at 550 nm. The results are shown below. If the standard solution (compound X) used have a concentration of 1 mM:1. Calculate the quantity of the standard compound X in μmoles for each test tube (1-7).
- In UV/Visible spectrophotometer analysis for a multicomponent system, there are only two dyes used in the mixture, the two proportions should be totalled to 1.0. but on finding You got 0.6 in total. Explain the reasons for the difference.what conclusions can you make based solely on this experimental results?It was found that the units on the ocular micrometer and the units on the stage micrometer matched up 40 units to 1.0 mm at 100 power. (So 40 ocular units equals 1.0 mm.) If the wing of a dead fruit fly was measured to be 2.5 ocular micrometer units at a magnification of 100, what is the length of the wing in mm?
- what analysis can be gathered from the raw count section and also what can also be said for the whole data as a whole. 500 words in total pleaseIt was found that the units on the ocular micrometer and the units on the stage micrometer matched up 40 units to 1.0 mm at 100 power. (So 40 ocular units equals 1.0 mm.) If the wing of a dead fruit fly was measured to be 2.5 ocular micrometer units at a magnification of 100, what is the length of the wing in mm? What does mm stand for?A TCL was run with 5 subjected samples utilizing a silica plate and ethanol/chloroform in mobile phase. The measured distance are shown in the picture. 1. The most polar sample in the 5 subjects is? 2. The least polar sample in the 5 subjects is? 3. Find the Rf value of Sample C and B
