Impact of a water Jet science laboratory - testing ground Report ExampleThe term molar mass of a given substance is much used to refer to the mass of one mol of a substance (Computer-Based Laboratory, 2007). In mathematical terms, it is a lot expressed as an average molecular(a) mass of molecules in the given substance when multiplied by Avogadros constant often approximated as 6.0221023. It can be shown molar mass = (1/6.022) 10-23g/u) (6.0221023/mol) average molecular mass (Lide, 2005).This experiment was trammel up to use the freezing point depression to adjust the molecular mass of benzoic acidulent. This was possible by first determining the freezing point of pure lauric acid and lauric- benzoic mixture, then calculating the molality of solution and the moles of benzoic acid as shown below.In this lab Experiment the apparatus and materials used included Lab Quest , Lab Quest App Temperature Probe, two 18 150 mm test provides 400 mL beaker, ring stand, paper towel or wind 4 1, Lab Quest 4, lauric acid, CH3(CH2)10COOH lauric acid-benzoic acid mixture hot water bath and the utility clamp.In this experiment the procedure was as follow. The initial step involved obtaining and wearing goggles. This was followed by connecting the Temperature Probe to Lab Quest and choosing New from the File menu. For the case where one had an older sensor that does not auto-ID, manually, he/she had to set up the sensor. The next step involved dabping the graze on the Meter screen, then changing the data-collection rate to 1 sample/second and the data-collection length to 600 seconds. This was part one of the experiment in which one had to determine the Freezing Temperature of Pure Lauric Acid. After this part, the next procedure was to add about 300 mL of tap water with a temperature of 2025C to a 400 mL beaker and then placing the beaker on the base of the ring stand. The utility clamp was then used to obtain a test tube containing hot, melted lauric acid from t he instructor while making sure
