What do you call it when the empirical and molecular formulas are one in the same?
I don't think there is a particular vocab word to describe when the empirical and molecular formulas are the same.
If the empirical and molecular formula are the same, that means that the empirical formula found is actually the molecular formula. This would be the case if the molar mass of the empirical formula found is the same as the molar mass of the molecule/compound given to you. If you were to divide the Molar mass given by the empirical it would equal 1 making the empirical formula actually the molecular formula. I don't think there is a specific name just that they would be the same.
Hi! I'm not aware of a particular saying for when they're the same. However, it's definitely possible that the molecular formula ends up without any subscripts that can be reduced (to integers), making it the same as the empirical formula.
Thanks guys. I think it might just be called the molecular formula if they are equivalent tbh but I don't think that will be very important to know considering that he hasn't mentioned it. Also, is the only reason of having the empirical formula to find the molecular formula or is there something else important about having that reduced ratio of atoms in the molecule?
