Solution
The correct option is D 23:35.5
Since Mass Ratio of H:Cl=1:35.5 in HCl and Na:H=23:1 in NaH, and
So, for 1 gm of H we are having 35.5 gm of Cl and 23 gm Na
When two elements combine separately with a third element & form different types of molecules, their combining ratio is reciprocated if they combine directly. This is called Law of Reciprocal proportions.
Hence the ratio Na:Cl=23:35.5
Hence the answer is option (a)
