S

4.1 moles

Explanation:

The following data were obtained from the question.

Number of mole (n) =..?

Volume (V) = 101L

Pressure (P) = 2atm

Temperature (T) = 600K

Gas constant (R) = 0.0821atm.L/Kmol

The number of mole of the gas can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

2 x 101 = n x 0.0821 x 600

Divide both side by 0.0821 x 600

n = (2x 101) / (0.0821 x 600)

n = 4.1 moles.

Therefore, the number of mole of the gas in the container is 4.1 moles

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
