Question

ReLATIVE DENSITY OF A VOLATILE SUBSTANCE WITH RESPECT TO CH4 IS 4 ITSMOLECULAR WEIGHT WOULD BE...

Answer 1

Relative density = density of substance/
density of reference
and for gases, under identical conditions it becomes,
Relative density = mass of substance/
mass of reference
Acc to question,
4 = x / 16
x = 64

so, molecular weight of substance is 64.

Answer 2

Answer:

hey buddy , the answer is 64

Explanation:relative density=density of volatile sub/density of ch4.as their cdns are identical i consider their volume as same..

relative density of volatile substance wrt ch4 =MW of volatile substance/MW of ch4.

then now,

4=MW of volatile substance/16..........molecular weight of ch4 is 16..

4*16=MW of volatile substance

=64.

hope this works...mark this as brainliest if u think i deserve it..
