Title: finding a formula
Post by: LittleLee88 on February 25, 2006, 01:39:45 PM

ok..I have to find a formula and name it from what this question tells me..I found the answer but I don't know if I did it right so I'm just checking..You have a molar mass of 92.2g/mol. 91.1% of it is carbon and 8.9% of it is hydrogen. Write the formula and name it. I got C6H8..but I don't know how to name it...Is that right? and if it is could you help me name it? Thanks!

hmmm.... what would a molecule of C₆H₈ look like?

Show how you got that formula.

Formula looks OK, but is not enough to name the compound.

so you can't name it then?
