First off, please do not provide me with the answer to the problem (I need to know how to do these things... )
The problem is:
By titration, 15.0 mL of 0.1008 M NaOH is required to neutralize a 0.2053 g sample of an organic acid. What is the molar mass of this acid? An elemental analysis of the acid indicates that it is composed of 5.89% H, 70.6% C, and 23.5% O by mass. Determine the molecular formula of the acid.
I think I can figure out the second portion of the problem with out determining the first part by assuming I have a 100g sample and thus have 5.89g H, and so on. But the first part is throwing me off a little b/c I need to know the number of moles of each element to find the molar mass, no?
Any help would be greatly appreciated.
and yes I went to the tutor but he just had this dumb look on his face and no real answers.
