help me /g/
A 1.2L container of liquid nitrogen is kept in a closet measuring 1.0m*1.1m*1.9m.
Assuming that the container is completely full, that the temperature is 20.4 degrees celcius, and that the atmospheric pressure is 1.1atm, calculate the percent (by volume) of air that would be displaced if all of the liquid nitrogen evaporated.
Liquid nitrogen has a density of 0.807g/mL.
PV=nRT
not asking you to solve it, but where the fuck am i even supposed to begin this one?
They are asking for V (what VOLUME OF AIR IS DISPLACED)
You need to solve the ideal gas law for V.
To solve the ideal gas law, you need n, the number of moles, which can be deduced from the volume of liquid and density.
