Question 987423
"2 liters" only shows one significant figure.  This "2 liters" can be anything from 1.9 liters to 2.1 liters. Actually to be more strictly correct, the 2 liters can be between  1.5 liters and 2.4 liters.  Either of these bounds would be 2 to the nearest ONES place.


The biggest percent error  would be between 2 and 1.5, which is a volume error of 0.5 liters.


{{{((0.5)/2)*100=25*percent}}}


Another important question, especially in practice, is "how well can the volume be read for measurement?"
