Fill in the blank spaces:

(i) Carbon dioxide gas is __________ than air. [heavier/lighter].

Answer 1

• Molecular weight is the weight in atomic mass units of each of the atoms in the given formula is the molecular weight.
• While density is the measurement of how tightly a material is packed together. It is the mass per unit volume of the substance
• Carbon dioxide( ${\mathrm{CO}}_2$ ) gas is heavier than air.
• The Molecular weight and therefore the density (at the same temperature and pressure) of ( ${\mathrm{CO}}_2$) is only marginally higher than the average density of air.

Therefore, Carbon dioxide gas is heavier than air.
