    I can't tell if you're doing it wrong or right without more detail but.. 

    .. .. .. . .. .. .. .. .. .. ... ...  ... ... .. .... 2*35.45 

    .. mass %Cl in SOCl2 = ---- ----- ---- ---- ----- ---- ----- x 100% = ?

    .. ... ... ... .... ... ... ... ... .. . 32.06 + 16.00 + 2*35.45

    you get to finish
