Question

chloride ion of a metal contains 71% cl by weight and the vapour density of it is 50. the atomic mass of the metal will be ?​

Answer 1

Answer:

W=29.

Explanation:

Say compound is MCly and weight of atom is W. ( By cross multiplication method of charge of ions you can easily figure it out that compound can be written in MCly form).

Molecular weight = 2x vapour density= 2x50. = 100g

Weight of Chlorine is 71% by weight so,

yx35.5 =71 so, y=2

Now we have

W + 35.5y =100

W+ 71 =100

W= 29.
