Unformatted text preview: DHAVAL RANA Period 7/8 Predicting Product Results Sheet: 40 Objective : Design a lab that allows you to predict the amount of sodium chloride that is formed when sodium hydroxide is added to hydrochloric acid and explain the theory of any calculations.. Results : Data Table 1 Mass of larger beaker 112.31g Mass of larger beaker and NaOH 112.84g Mass of NaOH 0.53g Result of pHydrion paper Blue Mass of large beaker and salt crystals 112.96g Mass of large beaker 112.31g Mass of NaCl 0.65g Amount of NaCl that should be formed 0.775g Percent error 16.1% Percent yield 83.9% Calculations : Mass is the amount of matter in an object. Mass is determined by multiplying volume by density or by using a balance. The unit for mass is grams. Percent error is finding out how off the observed answered was to the actual answer. Subtract the actual answer from the observed answer, divide by the actual answer, and multiply by 100. The percent yield is found out by diving the actual answer by the observed answer and then multiply by 100....
