A student prepares a 0.40 mM aqueous solution of acetic acid (CH,CO,H). Calculate the fraction of acetic acid that is in the dissociated form in his solution. Express your answer as a percentage. You will probably find some useful data in the ALEKS Data resource. Round your answer to 2 significant digits.
