Two one-cent coins were weighed on an electronic balance of high sensitivity, and an average mass per coin of 2.4918 grams was obtained from the data. How could you use an electronic balance of intermediate sensitivity to obtain an average mass per coin that contained the same number of significant figures as the value obtained using the high sensitivity balance?
a. Weigh a group containing more than two coins.
b. Weigh a two-coin group but estimate the balance reading to 0.0001 grams.
c. Weigh the two-coin group on two different intermediate sensitivity balances and average the results.
d. None of the three techniques described above will work.
