What is the volume of 5.6 moles 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 = 5.60 moles
R = 0.0821
T = 273 K
#V = 125.51 L
The second method is to us Avogadro's Volume at STP
In both cases the significant digit count is three figures which means the acceptable solution is
I hope this was helpful.
