laboratory involved utilizing equipment to dilute a sugar water solution. It also created solutions containing varying levels of concentrations and densities. Equations were used to figure the molecular weight of the sugar‚ and the number of moles of sugar in the volumetric flask. There was also an equation to figure the Molarity‚ as well. As a result of the experiment‚ I now have a better understanding of the density of a concentration‚ and what Molarity is . Observations Data Table 8: Initial Concentration

Refining Solutions Meghan L Adams PHL/458 July 16‚ 2013 David Boswell Refining Solutions There are a number of solutions that can be reviewed to solve most any problem and most require a touch of creative or critical thinking. William Hughes once said‚ “If we are not prepared to think for ourselves‚ and to make the effort to learn how to do this well‚ we will always be in danger of becoming slaves to the ideas and values of others due to our own ignorance.” This quote is one that can be considered

11 Service Department and Joint Cost Allocation Solutions to Review Questions 1. Companies allocate costs to estimate or assess the costs of their activities (products‚ processes‚ etc.). It is an estimate and subject to the problem that cost allocation contains an arbitrary element. Not allocating costs‚ however‚ is also an estimate—an estimate of zero. This may be appropriate for some decisions‚ but not for others. Some of the disadvantages (costs) include: (1) Additional

Is GREXIT A Solution? Vasudaiva Kutumbakam- the entire world is one family. But sometimes to this family disruptions are caused. What is important here is to stand strong and united against all the adversities just like the financial crisis of 2008 played a significant role in disrupting this single large family as it caused failure of key businesses‚ declines in consumer wealth estimated in trillions of U.S. dollars‚ and a downturn in economic activity leading to the 2008–2012 global recession

Economic Crisis: Solutions Global crisis is clearly felt nowadays‚ not only by third world countries but also by the richer and industrialized countries. Uprisings are recurring in different parts of the world by people who want change and a better life. Even in our country‚ the crisis is getting heavier each day. But then the real question is not the “what”‚ but more so‚ the “how”. How do we really resolve this problem? It is not unknown to us that the Philippines is in fact a country rich in

Concentration of a Solution: Beer’s Law The objective of this experiment is to determine the concentration of an unknown copper sulfate solution. You will be using the Colorimeter. In this device‚ red light from the LED light source will pass through the solution and strike a photocell. A higher concentration of the coloured solution absorbs more light (and transmits less) than a solution of lower concentration. The Colorimeter monitors the light received by the photocell as either an absorbance
