Carbon dioxide gas (CO2) has a molar mass of 44 g/mol. The two major components of air,
which are oxygen and nitrogen, have molar
masses of 32 g/mol and 28 g/mol, respectively.
Calculate the room-temperature densities in
g/L of nitrogen (N2), oxygen (O2), and carbon
dioxide (CO2) gases.

Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide as shown below. caco3(s) cao(s) + co2(g) the kp for this reaction is 1.16 at 800°c. a 5.00 l vessel containing 10.0 g of caco3(s) was evacuated to remove the air, sealed, and then heated to 800°c. ignoring the volume occupied by the solid, what will be the mass of the solid in the vessel once equilibrium is reached?
