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

purpose of this memo is to describe the sampling process and illustrate how sampling can be used during an audit. This memo will begin by defining what sampling is‚ when it should be used‚ and the risks associated with it. The memo will then continue to describe the basic steps involved with sampling‚ define terms within those steps‚ and describe the use of sampling in the audit by identifying two situations in which sampling is used in an audit. Sampling is the objective of which is to make a statement
