Vapour density of mercury with respect t...

Vapour density of mercury with respect to air is 6.92. calculate the number of atoms present inn each molecule of mercury vapour. (Given: Hg=200 and relative density of air=14.5).

Text Solution

Verified by Experts

Vapour density of merucry`=6.92xx14.5=100.34`
Molecular mass of mercury vapour
`=2xx100.34=200.68`=atomic mass of mercury
`therefore` Number of atoms in each molecule of mercury vapour=1.
