Why should the selected rule(s) be followed? Weighing wet items will cause the displayed mass to be greater than the actual mass of the object. A residue left on the balance will contaminate the balance pan surface and anything that comes into contact with it afterwards. Objects at any temperature other than room temperature can create air currents which can affect the balance pan, causing the measured mass to be higher or lower than the true mass. There may be discrepancies in accuracy between individual balances.
Three trials for this experiment had been conducted and the following are the masses of limiting reactant: 0.285 grams, 0.299 grams, and 0.292 grams. What is the standard deviation for the masses of limiting reactant for the three trials? please show work on how to do.
Calculate the value and report to the proper number of significant digits (you may need to round your answer). Calculate the % error (or % relative error or % inherent error) and the absolute error.
