What volume is occupied by 12 moles of nitrogen molecules at standard temperature and pressure?
a 371.1 liter
B 440.8 liter
C 221.4 liter
d 268.8 liter

V = 268.8 L

Explanation:

Given data:

Number of moles of nitrogen = 12 mol

Temperature = 273 K

Pressure = 1atm

Volume occupy = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

1 atm × V = 12 mol ×0.0821 atm.L/ mol.K   × 273 K

V = 268.95 atm.L / 1 atm

V = 268.8 L
