If the vapour density of a gas is 32, what is its molecular weight?

Key Points

• The vapour density of a gas is defined as half of its molecular weight.
• The formula to calculate molecular weight from vapour density is: Molecular Weight = 2 × Vapour Density.
• Given the vapour density of the gas is 32.
• Using the formula: Molecular Weight = 2 × 32 = 64.
• Therefore, the molecular weight of the gas is 64.

Additional Information

• Vapour density is a useful concept in determining the molecular weights of gases and is often used in chemical calculations.
• It is important to remember that the molecular weight of a substance is the sum of the atomic weights of all atoms in its molecular formula.
• Understanding vapour density can also help in identifying unknown gases and in calculating their molar masses during laboratory experiments.
