What is the pressure of 5.0 mol nitrogen gas in a 2.0 L container at 286 K
g100num [7]
The "Ideal Gas Law Equations" is 
PV=nRT
P= Pressure (in Pascals)
V=Volume (in Liters)
n=amount, or <u>n</u>umber (in moles)
R= 8.3145 \frac{Pascals*Liters}{Moles*Kelvin} or \frac{PaL}{molK}
T= Temperature (In Kelvin)

P= \frac{nRT}{V}

Plug into the equation and you're good!
P=\frac{nRT}{V}
P =\frac{(5mol)(8.3145)(286K)}{2L}
P=5944.8675Pa

If your teacher cares about sig figs,
2 sig figs (significant figures)
P=5900Pa

For other units of pressure,
1 atm = 760 mmHG = 760 Torr = 101326 Pa = 1.01325 bar<u />
