Did the chemist make the correct choice in how they choose to display the data up in Table
1? Choose the best explanation from the choices below.
No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated.
Doing so would eliminate significant information.
No. Since the instrument calculates 5 decimal places for the standard, all of the values should be
limited to the same number. The other decimal places are not significant for the blank and unknown
sample.
Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware
can report values to 2 decimal places, and this establishes our number of significant figures.
Yes. Instrumental data…
