Question

Equivalent weight of element x is 3.If vapour density of volatile chloride of x is 77.The molecular formula of chloride is?

Answer 1

Answer:

mark me brainliest

Explanation:

mark me brainliest

Vapour density=1/2 molecular weight

Therefore, molecular mass of the chloride = 77×2 = 154.

Also, molecular mass of the chloride =3×x+x×35.5 ( where x is the valency of the element).

On solving, we get x =4.

Therefore, atomic mass = 4×3 = 12
