Carbon dioxide (CO) is a gaseous compound. Calculate the percent composition of this compound. Answer using three significant figures.
What is the percent by mass of carbon?
%
What is the percent by mass of oxygen?
%

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
