Nitrogen gas makes up almost 80% of our atmosphere.What is the density of pure nitrogen gas,in g/L,at 12.50 degree and 126.63 kPa?
答
Greetings!Use the Gas Law:PV=nRT.Therefore,n=PV/(RT)=1.25atm( you gotta convert kPa to atm) *V (you don't have to calculate this cuz you'll never know) / ( .0821 L atm mol^-1 K^-1 * 285.65K) =.053301*...
