An oxide XO2 has a vapour density of 32. What is the atomic mass of X?

the atomic Mass of X is 32

Explanation:

To solve the atomic mass of X, we must first calculate the molecular mass of XO2. This can be done by:

Molecular mass = 2 x vapour density

Vapour density of XO2 = 32

Molecular mass = 2 x 32 = 64

From the above, we can calculate the mass of atomic mass of X by doing the following:

XO2 = 64

X + 2O = 64

X + (2x16) = 64

X + 32 = 64

X = 64 — 32

X = 32

The atomic mass of X is 32. X is therefore sulphur.
