wont it be C4H16N2

dtan5457 · Answer

Trying to get the molecular formula right?

dominantvampire · Answer

yes, i am

kyanthedoodle · Answer

Isn't it the same? Isn't it still C2H8N?

dtan5457 · Answer

Yeah, if the molecular mass is 46 grams, your empirical is identical. Recheck your question.

dominantvampire · Answer

the answer of this question is the same as written above 
i am doing molecular and emperical formula calculation practice thru online worksheet and 
isn't molecular formula DOUBLE the emperical formula

dominantvampire · Answer

compound with an empirical formula of C4H4O and a molar mass of 136 grams per mole.  C8H8O2    just like this

dtan5457 · Answer

There is no specific formula for molecular formula. It all depends on the molar mass. If the molar mass was 92 grams, then yeah, you would double it.

dtan5457 · Answer

Or if it was 144, you would multiply everything by 3.

dtan5457 · Answer

However yours is still at 46..so, it's the same.
