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

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

the right answer is c i just did the question.
