    measured to the center of the object’s mass and the acceleration due to gravity “g”. By rearranging this expression it s possible to derive the following. As seen from the expression‚ a plot of pendulum length verses its period squared will yield a straight line. The slope will be dependent upon the local acceleration due to gravity (9.803 m/s2) Procedure: Since the length to be used in this experiment is the distance to the center of the pendulum’s mass‚ the diameter of the bob is estimated

    Abstract: All the materials were measured and weighed. It was found in the experiment that the yield of copper hydroxide in 40%. Introduction: The copper (II) sulphate is then placed in 100 mL of distilled water. Then 20 mL of CuSO4 is measured and placed 100 mL of distilled water. This can later be weighed to determine the mol of CuSO4 and the mol/L concentration. Then this was used to find out how many mL of 0.5 NaOH solution is needed to react completely with all the copper (II)

    be: 2Fe (Ш) + 3CuCl2 (aq) → 3Cu + 2FeCl2 In addition‚ we will need to find the percent yield of copper. Percent yield is a measure of the mass of what was produced ("experimental yield") divided by the mass of what should have been produced ("theoretical yield"). Hence‚ the equation will be: Percent yield= experimental yield theoretical yield We will need to substitute the experimental yield and the theoretical yield of copper after we have found out the actual equation. Purpose Since there are

    theoretical yield of your product? Theoretical yield of the CaCO3 is expected to be .69g. B. According to your data table‚ what is the actual yield of the product? The mass of the filter paper was 1.1g‚ and the total mass of the filter paper when dried with the CaCO3 was 1.8 total. Thus the actual yield of the product was .70g. C. What is the percent yield? Percentage yield is actual yield over the theoretical yield x100. Actual yield: .70gTheoretical yield: .69g percentage yield: 101%
