Ascientist measures a substance to be 0.6 grams. calculate the percent of error in the measurement. show all work for full credit.

A measurement of 0.6 grams means that the 'true' answer lies between
0.55 and 0.65 

In general, the uncertainty in a single measurement from a single instrument is half the least precise decimal given for the instrument.
The precision for this measurement is in the tenths place.
so we take 0.1 /2 = 0.05, and divide by the measurement

0.05 / 0.6 = 0.08333 = 8.3 %

1. 3/6 or 1/22. 1/123. 1/84. 1/105. 2/12 or 1/6
