Question

The density of gaseous element is 5 times that of oxygen, under similar conditions. if molecule of element is triatomic. what will be its atomic mass

Answer 1

If the density of the gas is 5x oxygen then the molecule weight is 5 ... but unknown molecule is triatomic hence atomic mass of it=32 x5/ 3 ?

... element is 5 times that of oxygen under identical conditions . if the molecule is triatomic . what would be its mass.
