**1. The problem statement, all variables and given/known data**

What is the density of nitrogen gas at a temperature of 20 degrees celcius

**2. Relevant equations**

p= m/v??

Pv=nRT??

change in volume = (volumetric coefficicient of thermal expansion)(initial volume)(change in temperature)??

**3. The attempt at a solution**

i tried to use the coefficient of thermal expansion to find the changing volume but gasses dont have values for thermal expansion.

now im not sure what to do

any help is appreciated
