Mass Calculations

Calculation of Mass of Solids by dint of Calculation John Holmes instructor: Joe Blow October 23, 2010 enjoyment/INTRODUCTION The purpose of this try bulge is to specify the mass of copper (Cu) and press (Fe) idles and a cognise quantity (1.1 g) of Sodium Chloride (NaCl) and in the treat expose weaknesses in meter techniques and possible variations in measurements collectable to differences in equipment sensibility and standardization. In order to correctly determine the mass of the solids in question a methodology of compute measurement, contrastiveial measurement and calculation by averaging were implemented. In the conductivity of the experiment centigram relief scales, electronic scales were utilized to measure and temper the mass of the bodily. In some cases the material was orient weighed on the scales and in separate cases the material was differentially weighed by placing the material in a beaker or watch ice rink therefore advisement the beaker o r watch glass and material unneurotic because weighing the beaker or watch glass unload and subtracting that clog from the combined weight of the beaker or watch glass and the material. enter data shows that scales of the same type may award different readings primarily as a result of calibration error. As well differences in measured mass grass be attributed to the sensitivity and accuracy of the instruments used.

Calculated average set were obtained by weighing multiple swigs of copper (Cu) simultaneously through the direct measurement method and dividing that measured value by the total of slugs being we ighed. MATERIALS Materials required to c! onduct this laboratory experiment embarrass: * Centigram Balance Scales (2 each) * Electronic Scale * High aesthesia Scale * run across Glass * Beaker, 100 ml * Copper (Cu) Slugs (5 each) * Iron (Fe) weight (#1 from available lab samples) * Sodium Chloride (NaCl), 1.1g EXPERIMENTAL METHODS vicinity One: Measure the mass of a copper (Cu) slug on two centigram...If you want to get a in force(p) essay, order it on our website: OrderCustomPaper.com
