Answer: 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.
