Calculate the moles of N(2) in a 3.50 litercontainer at 1.15 atm pressure and 28 degrees C.
What is the Density of the gas?
What is the new pressure if the temperature is raised to 75 degrees C?
What is the new density of the gas?

density= mass/volume
moles=PV/RT change Temp to K
denstiy=moles*28/volume
