Answer to Question #248588 in General Chemistry for Lyn

Question

Lesson: ideal gas law

Solve problem

What is the volume occupied by 12 moles of nitrogen gas at STP?

Answer 1

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
