Scientists routinely use several different types of pressure gauges, and sometimes a single vacuum chamber may be equipped with more than one type of gauge, this should be explained. Concept introduction: Gauge pressure depends on the ambient atmospheric pressure for its measurement. The output of the gauge pressure sensor is directly influence by the weather conditions and altitude, as it changes the atmospheric pressure. If the gauge pressure is higher than that of the ambient pressure, it is referred to as positive pressure. Opposite to it, for pressure below atmospheric pressure, it is referred as negative or vacuum gauge pressure.

Question

we were assigned to dilute 900ppm in to 18ppm by using only 250ml vol flask. firstly we did calc and convert 900ppm to 0.9 ppm to dilute in 1 liter. to begin the experiment we took 0,225g of kmno4 and dissolved in to 250 vol flask. then further we took 10 ml sample sol and dissolved in to 100 ml vol flask and put it in to a spectrometer and got value of 0.145A . upon further calc we got v2 as 50ml . need to find DF, % error (expval and accptVal), molarity, molality. please write the whole report. thank you The format, tables, introduction, procedure and observation, result, calculations, discussion and conclusion

Chapter 5, Problem 5.80PAE

Interpretation Introduction

Interpretation: Scientists routinely use several different types of pressure gauges, and sometimes a single vacuum chamber may be equipped with more than one type of gauge, this should be explained.

Concept introduction:

Gauge pressure depends on the ambient atmospheric pressure for its measurement. The output of the gauge pressure sensor is directly influence by the weather conditions and altitude, as it changes the atmospheric pressure. If the gauge pressure is higher than that of the ambient pressure, it is referred to as positive pressure. Opposite to it, for pressure below atmospheric pressure, it is referred as negative or vacuum gauge pressure.

Q5. Predict the organic product(s) for the following transformations. If no reaction will take place (or the reaction is not synthetically useful), write "N.R.". Determine what type of transition state is present for each reaction (think Hammond Postulate). I Br₂ CH3 F2, light CH3 Heat CH3 F₂ Heat Br2, light 12, light CH3 Cl2, light No
