    The correct answers are 4.93 %, 4.72 % and 4.93 %.

    Explanation:

    Based on the given question, 14.41 g per ml is the actual density of the object. However, the density determined by three different students of the object is 15.12 g per ml, 15.09 g per ml, and 15.12 g per ml. The percent error can be calculated by using the formula,

    % error = (actual value - calculated value) / actual value * 100

    By 1st student, the calculated value is 15.12 g per ml, the percent error will be,

    % error = (14.41 - 15.12) / 14.41 * 100

    = 0.71/14.41 * 100

    = 4.93 %

    By 2nd student, the calculated value is 15.09 g per ml, the percent error will be,

    % error = (14.41-15.09) / 14.41 * 100

    = 0.68/14.41 * 100

    = 4.72 %

    By 3rd student, the calculated value is 15.12 g per ml, the percent error will be,

    % error = (14.41-15.12) / 14.41 * 100

    = 0.71/14.41 * 100

    = 4.93 %
