Question

What is the density of carbon dioxide at stp? 46.0 g/l 22.0 g/l 5.09 × 10-1 g/l 1.96 g/l?

Answer 1

Hello Dear.


Molar Mass of the Carbon dioxide = 44 g/mole.
[∵ 12 + 16 × 2 = 44]

Volume occupied by the Carbon dioxide at S.T.P. = 22.4 liter.

∵ Density = Mass/Volume
∴ Density of CO₂ = 44/22.4
⇒ Density = 1.96 g/l


Hence last option is correct. Thus, the density of the Carbon Dioxide at S.T.P. (Standard Temperature and Volume) is 1.96 gram/liter.


Hope it helps.
