what it would’ve been in the larger solvent as numbered in Data Table 4. There wasn’t much difference between the corrected number of moles and grams of urea and the amount of urea used originally used in the experiment‚ so the ammonium chloride will be primarily compared to the corrected amount of urea to make sure that the amount of solvent is equal. Graph 1 and 5 and Data Table 2 show that the mass of solutes were overall very similar: 8.735 grams of ammonium chloride and 8.99 grams of urea. Overall

How does ‘the world’ change as the light changes? When light intensity around us changes‚ we look at things differently. A man in a clown suit could seem like a symbol of happiness but in the dark could represent an eerie cover-up. As the sun was setting‚ there were a number of things that changed in terms of vision. The most obvious change was that objects became harder to make out. For example‚ a park bench in the distance witch was obvious before sunset became difficult to see after the sun

Extracting NaCl from Rock Salt and assessing its purity Aim The aim of this experiment was to obtain a pure product from a solution through the processes o extraction‚ filtering and evaporation. Introduction Extraction is used when trying to separate or purify a product. For an extraction to be successful the substance used to make the solvent should readily dissolve. The substance used in this practical was rock salt. The liquid used should not react with the substance that needs extracting

example the atomic mass of Na is 23 and the atomic mass of Cl is 35.5 so the relative formula mass of NaCl is 58.5 How by using RFM is it possible to work out amounts of a substance in terms of moles? The compound I was using in my experiment was NaOH. The first thing I needed to work out was the number of moles I needed. To do this I used the formula: Number of moles = Mass ÷ RFM. The mass is the amount that I weighed on the balance which was 1g. I then worked out the RFM of NaOH which is 40. I next

How does water temperature affect the amount of dissolved oxygen? Ⅰ. Introduction Dissolved oxygen is just one of the many ways to measure water quality. It means the volume of oxygen that is contained in water. The amount of dissolved oxygen in water usually determines the quantity of organisms living in that water. Dissolved oxygen levels vary by how much oxygen the water can hold‚ how much oxygen is produced by photosynthesis‚ and how much oxygen is consumed by respiration. If water is too warm

whether or not the amount of air inputted into a soccer ball would affect the ball’s travel distance. Along with that‚ we hoped to learn which amount of air would deliver the furthest distance. And potentially with this knowledge‚ those who play the sport‚ will know to what amount they should fill their ball to‚ in order to gain the best performance‚ distance wise. Although results may vary among players. This is just a general observation‚ with a certain and consistent amount of force. The experiment
