What is the volume occupied by 0.355 mole of nitrogen gas at STP?
There are two ways to calculate this if we assume STP of 1 atm and 273 K for the pressure and temperature.
We can use the Ideal Gas Law equations PV = nRT
P = 1 atm
V = ???
n = 0.355 moles
R = 0.0821
T = 273 K
#V = 7.96 L
The second method is to us Avogadro's Volume at STP
I hope this was helpful.
