When 6.0 mol of oxygen are confined in a 36l vessel at 196°c, the pressure is 8atm. what is the new pressure for oxygen expands at constant temperature to fill 48l

The new pressure for oxygen gas is 6 atm.

Explanation:

To calculate the new pressure of the gas, we use the equation given by Boyle's Law.

This law states that the pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

Mathematically,

or,

where,

are the initial pressure and volume of the gas.

are the final pressure and volume of the gas.

We are given:

Putting values in above equation, we get:

Hence, the new pressure for oxygen gas is 6 atm.

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.
