    C) 7.5%

    Explanation:

    Accepted value of a substance can be said to be that number or "value" that is generally accepted by scientists worldwide.

    Experimental value is that value is a substance that is gotten from experiments in the lab.

    Experimental error then is the percentage difference between the accepted value and experimental value.

    Percentage error = [ (|experimental value - accepted value|) / (accepted value) ] * 100%

    Percentage error = [ (|37 - 40|) / 40] * 100%

    % error = 3/40 * 100%

    % error = 0.075 * 100

    % error = 7.5%
