    Answer:

    3ppt is the relative error of the method

    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
