Four students are asked to find the mass of a mineral using a calibrated balance. the results were as follows: 16.009 g, 15.780 g, 16.110 g, and 15.990 g. the known mass of the mineral is 16.100g. which student's result was the most accurate? the results were 16.009 g 15.780 g 16.110 g 15.990 g

Known result = 16.100 g
For a measurement of x g, the % error is calculated s


Create a table that calculates the %error for each measurement

          x  %error
----------  ---------
16.009   0.565
15.780    1.988
16.110     0.062
15.990   0.683

From the calculated results, it s clear that the measurement of 16.110 g has the least error, and it is, therefore, the most accurate.

The most accurate measurement is 16.110 g.
