Homework Help: chemistry

Posted by helpp on Saturday, August 30, 2008 at 3:11am.

In a laboratory experiment, the density of a concentrated sugar solution was determined by measuring the volume of the solution and corresponding mass. Three students each made a set of measurements using a different balance and used the results to calculate density. Their results are summarized here.

Part2, rank from most to least accurate
error=(average measurement)-(accepted value)

what is the accepted value?

Density (g/mL)
Trial Set 1 Set 2 Set 3
a 1.380 1.347 1.346
b 1.400 1.479 1.499
c 1.374 1.401 1.301

Rank the data sets in decreasing order of precision

I know that your supposed to use this formula

deviation=(individual measurement)-(average measurement) this is all in absolute value, so its always positive.
