1.0 moles of an ideal gas are held in a container under 2.0 atm of pressure and 310 K. What must be the volume of this container?

12.7 L (3 s.f.)

Explanation:

Since it is an ideal gas, we can apply the ideal gas law:

☆ where p= pressure

V= volume

n= number of moles

R= ideal gas constant

T= temperature

Substitute all the given information into the formula:

2V= 1(0.08206)(310)

2V= 25.4386

V= 25.4386 ÷2

V= 12.7 L (3 s.f.)

Further explanation:

The ideal gas constant, R, has different values depending on what units are being used. Two examples are listed below:

In the above question, we use the value 0.08206 because the pressure was given in atm and the temperature was given in Kelvin. Thus, the unit used for volume is L.

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.
