Significantly affects the calculation of r in the experiment

Reference no: EM13170397

In this experiment we evaluated R, the gas law constant. PV=nRT

Most top-loading balances used in this experiment measure a mass only to the nearest mg(+/- 0.001 g). This significantly affects the calculation of R in the experiment. Explain why this is so. How might the procedure be modified to compensate for this systematic error?
