Question

15. The vapour density of gaseous element is 5 times that of oxygen under similar conditions of
temperature and pressure. If the molecule of the element is triatomic, what will be its atomic
mass?​

Answer 1

Answer:

It is given that the vapour density of the

unknown gaseous element in 5 times that vapour density of oxygen. The formula for atomic mass is now to calculate the atomic mass of the Unknown element we will divide the molecular

mass by the atomic of the Unknown element.
