1. What do you feel is the largest source of experimental errorin your determination of R?
2. What would be the effect (increase, decrease, or no change)on the calculated value of R of each of the following experimentalerrors? a. The liquid level in the eudiometer tube is lower thanthat in the beaker, but this is not taken into consideration in thecalculations.
b. The balance used to weigh the magnesium gives a mass that ishigher than actual.
c. Some H2 escapes into the beaker during the reaction.
3. Most top-loading balances used in this experiment measure amass only to the nearest mg ±0.001g. This significantly affects thecalculation of R in this experiment. Explain why this is so. Howmight the procedure be modified to compensate for this systematicerror?
