How would you record a measurement of 16490 grams using only 2 significant figures?
The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". When 16490 is rounded off to 2 significant figures then the first figure to be discarded is 4. As this is less than 5 then the previous figure (6) is not increased by 1. 16490 to 2 significant figures is 16000.

0.00755 Any zeros that are before an additional number do not count. Thus, "0.00" would not count as significant figures. The first significant figure is the "7", with the "5" following it. With the second five (in my answer), "4" was rounded up to "5" because the number behind the "4" was a "6", thus the "4" rounds up.
