volumetric glassware and the accuracy of measuring the volumes of liquids very precisely in quantitative laboratory work. The accuracy of the measurement the volumes is the degree of closeness of measurements of a quantity’s actual volumes while the precision of the volumes is the degree to which repeated measurements under unchanged conditions show the same results. Each of volumetric glassware is marked with its total volume‚ the notation of TD for ‘to deliver’ and TC for ‘to contain’ and also with

Financial accounting reports are prepared for the use of external parties such as shareholders and creditors‚ whereas managerial accounting reports are prepared for managers inside the organization. This contrast in basic orientation results in a number of major differences between financial and managerial accounting‚ even though both financial and managerial accounting often rely on the same underlying financial data. In addition to the to the differences in who the reports are prepared for

Part I: Density of Unknown Liquid 1. Calculate the mass of the liquid for each trial. (Subtract the mass of the empty graduated cylinder from the mass of the graduated cylinder with liquid.) Trial 1 36 - 25.5 = 10.5 Trial 2 36.5 - 25.5 = 11 Trial 3 36.9 - 25.5 = 11.4 2. Calculate the

g/cm^3. The results for this experiment prove that as you increase % of NaCL‚ the density increases also because of the weight of NaCL is increased. Graph #1 shows that as the %NaCL increased so did the density‚ therefore proving the accuracy and precision of part II calculations. In part III‚ of the experiment‚ the density of regular shaped objects‚ were calculated based on volume measured method and water displacement method. My hypothesis for this part of the experiment was that volume measured

‘Formality’ is very important‚ as academic writing is to inform the reader on a subject‚ it is not to be entertaining. Writing should be up to a formal standard‚ like broadsheet papers‚ textbooks and journals. As writing has to be a high standard‚ ‘Precision’ should also be considered. However this type of writing might be more relevant to scientific writing‚ giving facts and figures precisely. There is however a general rule that applies to all types of academic writing‚ which is objectivity. All academic

Lab No.1: density‚ accuracy and precision Aim: to determine the relative precision and accuracy of different glassware items by calculating the density of a known substance. Introduction: the density of a substance is its mass per unit volume. (where P-density‚ m- mass and v- volume). Different materials usually have different densities and densities vary according to the pressure‚ temperature and purity of a substance. When measuring‚ there is always a small uncertainty or error and therefore
