Question

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

Answer 1

16.110 g

Step-by-step explanation:

Answer 2

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

`\% error= 100((|x-16.100|)/(16.100) )`

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.

Answer:
The most accurate measurement is 16.110 g.
