Part A- Preparation of p-Acetotoluidide • After completing the experiment‚ a yield of 0.21 g of a pure white crystal were collected from the Buchner funnel‚ and when compared to the calculated theoretical yield‚ 0.82 g (found in Calculations 1.A)‚ a percent yield of 25.4% can be calculated for this procedure. Although this value may not seem favorable for this procedure‚ when compared to the expected value described by the laboratory manual‚ which was 0.4 g‚ it can be seen that the procedure performed

in a fluid was discovered in 1827 by Robert Brown. The theory of the Brownian motion and the atomistic backgrounds of diffusion were developed by Albert Einstein. Now‚ the concept of diffusion is widely used in science: in physics‚ chemistry and biology‚ in sociology‚ economics and finance . It appears every time the concept of random walk in ensembles of individuals is applicable. History of diffusion in physics In technology‚ diffusion in solids was used long before the theory of diffusion
