a compound is found to be 94.1% o and 5.90% h. its molecular mass is 34.0. what is its molecular formula

A. H3O2
B. OH
C. H2O
D. H2O2
I think D

  • chemistry -

    You didn't show your work so I can't comment on that; however, the answer is right. I note, with some amusement, that D is the ONLY answer with a molar mass of 34. But that isn't the way to work the problem.
