When Barium metal is heated in chlorine gas, a binary compound forms that consists of 65.95% Ba and 34.05% Cl by mass. Calulate the molecular formula of this compound if the molecular weight is 416.4 g/mole.
Because, atomic wt of Ba = 137
and atomic wt of Cl = 35.5
If I take a 100 gm of the mixture,
Ba = 65.95 gm = ...
The solution gives the steps necessary to work out the molecular formula of the binary compound formed when barium is heated in chlorine gas, given its weight.
