The molar volume of liquid benzene is 0. 0889 dm3 at 20oc atm 1 atm pressure. Assuming the volume to be constant, find g and a for compression of 1 mole of liquid from 1 to 100 atm

Respuesta :

The molar volume is the ratio of the moles to the density. The value of G at constant volume is 891.5 J and A is 0.

What is molar volume?

Molar volume is the volume that is given by the moles of the substance that are present at a given pressure and temperature.

When the temperature and pressure are constant then, the change in volume is 0.

Δ A = - P ΔV

= - P × 0

= 0

Given,

Molar volume = 0.0889 dm³

Initial pressure = 1 atm

Final pressure = 100 atm

ΔG is calculated as:

ΔG = V (P₂ - P₁)

0.0889 × (100 - 1)

= 8.8011 atm

To convert it into Joules:

8.011 × 101.3 J = 891.5 J.

Therefore, G is 891.5 J and A is 0.
