Answer 1

Answer:

16

Explanation:

Given Vapour density of a gas is 16. The ratio of specific

heat at constant pressure to specific heat at constant

volume is 1.4, then its atomic weight is

We know that Cp / Cv = r , r = 1.4

Now the gas is diatomic, so atomicity is 2.

Now molecular weight = 2 x vapour density

                                    = 2 x 16

                                   = 32

So atomic weight = molecular weight / atomicity

                            = 32 / 2

                          = 16

Answer 2

Answer:

hey  buddy , the ans is 16

Explanation:

r=1.4(which indicates tht the element is diatomic , so if u want its atomic weight then u have to divide the molecular weight by 2(as it is diatomic))

so now,

molecular weight=2*vapour density.

then molecular weight is 16*2=32.

as i have already mentioned , to get atomic weight divide the molecular weight by 2.

then the atomic weight would be 32/2=16.

hope this works..

mark me brainliest if u think i deserve it..
