It turns out that the van der waals constant b equals four times the total volume actually occupied by the molecules of a mole of gas.
using this figure, calculate the fraction of the volume in a container actually occupied by ar atoms at 230 atm pressure and 0 c. assume b=0.0322 l/mol

0.0826 of the volume in the container is actually occupied by Ar atoms

Explanation:

First we find volume occupied by 1 mole the gas using Ideal gas equation

PV = nRT

Given:

P - 230 atm

R - 0.0821 atmL/molK

T - 0 C or 273 K

n - 1

V - Vg (Volume occupied by 1 mole of gas)

Therefore,

Vg = 1 * 0.0821 * 273 / 230 = 0.09745 L

Then we find the volume actually occupied by 1 mole of Ar atoms - Va

b = 4Va

Therefore,

Va = 0.0322 / 4 = 0.00805 L

The fraction of the volume in the container actually occupied by Ar atoms is

= = 0.0826

Therefore, 0.0826 of the volume in the container is actually occupied by Ar atoms

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
