Question

To check the accuracy of a new method, a standard copper alloy containing 23.24% Cu was analyzed and calculated to contain 23.17%. calculate the relative error of the method in parts per thousand (ppt).

Answer 1

3ppt is the relative error of the method

Step-by-step explanation:

The relative error is a measurement used to determine the accuracy of your experiment, the equation to find the value in parts per thousand is:

Error = |True Value - Observed Value| / True Value * 1000

Where True value is 23.24%

And Observed value is 23.17%

Replacing:

Error = |23.24% - 23.17%| / 23.24% * 1000

Error =

3ppt is the relative error of the method
