Answer 1

Answer:

Option 1)

Explanation:

Look here,

Na = 23u

Cl = 35.5u

So that's the only possible answer.

Answer 2

Answer:

Since, mass ratio of H:Cl=1:35.5 in HCl and Na:H=23:1 in NaH.

And since according to law of constant proportion compounds always contains its elements in a fixed ratio by mass.

So, for 1gm of H we are having 35.5gm Cl and 23gm Na.

Hence, the ratio Na:Cl=23:35.5

Hence, the answer is option A.
