Density Lab

ABSTRACT In the assiduousness, Accuracy, precision and Graphing experiment, the purpose was to see to it the niggardliness of peeing and the closeness of a saline response as considerably as to compare the accuracy and precision of a gradatory cylinder and a receive pipet. Based on the operating instructions of the lab manual, Fundamentals of Chemistry, the experiment was performed in trio betters, come out A: Density of Water-The meanness of water was calculated by measuring the large number of troika different volumes: 10mL, 30mL and 50mL. air division B: Accuracy and Precision was performed using a 100mL beaker, 10mL graduated pipet and deionized water. The experiment was performed three times; each time, 10mL of water was added to the beaker and recalculated. sort C: Density of Sodium Chloride (NaCl) Solution, a sample of NaCl was obtained and deliberate using a 100mL beaker and a 10mL pipet to determine the immersion of the root word. In order of magn itude to obtain the appropriate result, a standardisation graph and density measurement was used to determine the concentration of the sodium chloride solution. In conclusion, based on the water temperature of 21.8°C in part As graduated cylinder experiment obtained, it was immovable that the average density was .0973g/mL with a percentage phantasm of 2.5%. When graphed the measurement was equal to Y=0.988x.

Part B: The graduated pipets average density at 22.3 °C was determined to be 0.9785g/mL with a percentage illusion of 1.89% shows the graduated pipet to be more(prenominal) accurate and precise. Part C: Density of an unknown NaCl solution was measured and a calibration curve u sed to determine the percentage of NaCl by m! ass in the solution. y=0.007x + 0.998 which think that the concentration of the sodium chloride solution was 3.14%. INTRODUCTION Anything that you can see, touch, taste or smell, occupies space and has mass, it is called matter. subject field can be a gas, a liquid, or a solid. But density of the mass is an intensive property that be as the amount of mass in...If you privation to get a full essay, order it on our website: OrderEssay.net
