# Problem: At STP, what is the volume of 4.50 moles of nitrogen gas?A) 167 LB) 3420 LC) 101 LD) 60.7 L

###### FREE Expert Solution

We are asked to find the volume of nitrogen gas (N2) at STP. At STP, we have 273.15 K for temperature and 0.98692327 atm for pressure

Since moles, temperature, and pressure are given, we will use the ideal gas equation to calculate for the volume.

$\overline{){\mathbf{PV}}{\mathbf{=}}{\mathbf{nRT}}}$

P = pressure, atm
V = volume, L
n = moles, mol
R = gas constant = 0.08206 (L·atm)/(mol·K)
T = temperature, K
