What information is given in the msds for acetic acid? the mass of acetic acid that is consumed in an experiment the volume of acetic acid that is needed for an experiment the cost of acetic acid at various concentrations the reactivity of acetic acid with various chemicals?

I believe the correct answer is its reactivity with other chemicals since the whole point of an MSDS is to tell you the characteristics and properties of the chemical in which you using.  For a lab you would go to the MSDS to learn how to use the chemical safely.  

The volume of acetic acid consumed would be found through knowing the amounts of reactants used and using stoichiometry to find how much should be consumed.

The volume of acetic acid to be used would be found in the procedure.

The price of acetic acid at certain concentrations would be found on an online distributor's web page.

I hope this helps.  Let me know if anything is unclear.

The answer should be vaporization
