Question

the ratio of carbon 12 atomic to that of an atom of element X ( whose atomicity is four ) is 1:9. The molecular mass of element X is

Answer 1

Given :
Atomic mass of carbon -12=12u
Molar mass of carbon -12=12g

The mass of 1 mole of carbon 12=12g

Ratio of carbon 12 atomic mass to that of X is =1:9

12/x=1/9X
=108g

The mass of one molecule of X atoms contains 9x12=108g
The atomicity=4

Thus , one molecule will contain 4 X atoms
Hence, the mass of 1 mole of compound will be 4x108=432g

The molecular weight of X will be 432g

Answer 2

Answer: 432 g
