Question

The vapour density of CH₃OH is ______.

(Atomic Wt. of C = 12, Н = 1, O = 16)

पर्याय

• 32

• 18

• 16

• 34

Answer 1

The vapour density of CH₃OH is 16.

Explanation:

The molecular mass of methanol (CH₃OH) is calculated by adding the atomic weights of its constituent atoms:

12 + (4 × 1) + 16 = 32 g/mol

Vapour density is defined as exactly half of the molecular mass of a gas.

∴ `32/2` = 16
