    Please help me solve the problem in the attachment.

    First of all, I don't understand exactly what equivalent weight is.
    Secondly, I know that the coefficient of variation is CV = (s/x) x 100%
    So, what does the % analyte formula in the problem statement have to do with anything?

    %A = tritrant volume x equivalent weight x 100/sample weight
    =>%A= (final -initial buret reading)*equivalent weight*100/sample weight

    Final reading F = 8.76 mL +- 0.03 mL
    Initial reading I = 0.23 mL +- 0.02 mL
    Sample weight W = 50 ...
