A 2.55-g sample of the gaseous product produced in a chemical
reaction was found to have a
volume of 0.45 L at 293 K and
1.1 atm. What is the molar mass
of this gas? Describe the steps.

try answer.com that works for me

if the temperature drops and becomes cool

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
