You receive two samples of a substance. After testing, it

shows that one sample contains 88% oxygen by mass an 12%
hydrogen. The second sample contains 94% oxygen and 6%
hydrogen. Is it possible that the two samples are the same?
Explain. thanks, I appreciate the help !

I suppose the obvious answer is that it depends upon the analyst doing the work; however, I think the spirit of the problem tells you s/he has the utmost accuracy and precision. From the way the problem is stated, the obvious answer would be yes they are the same; otherwise why ask the question. However, I think they are different.

94/16 = 5.87
6/1 = 6
If you round this the empirical formula is C6H6; if you don't it is C41/H42.

88/16 = 5.5
12/1 = 12
That is 11:12 or C11H12.
I don't see how they could be the same. but check my thinking. I've been wrong before.
