What is the identity of a gas with a density of 1.964 g dm-3 at 273 K and 76 cm Hg?
The density of a gas can be used to determine its molar mass. Using the ideal gas law and given conditions, we can calculate the molar mass of the gas. The molar mass of CO2 is 44 g/mol, which matches the calculated value based on the given density, confirming that the gas is CO2.
