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.

there all right good

explanation:

c is the answer because when something is left after something evaporates that shows the chemical change.
