There is definitely some typo in your post and some missing information that makes it impossible to solve/helpHmF2 + Hm produces some gas and we are expected to find the amount of the HmF2 produced?Is it intended to be Hm + F2 HmF2(g)?Even if so, we are not given any information to base the stoichiometry calculation on.
So it is a limiting reagent problem, isn't it?There is a slight problem with fluorine, volume is given but not conditions, so it is not clear how to convert volume to moles. Assume whatever STP you want, just state it clearly in your solution.
fluorine is held at STP
and after getting 4.52 L of HmF2 using stoichiometry
I need to determine how much of it is actual dry gas.
