Physics II / Systems, Walls and State Variables
Practice question · Numerical answer

A system contains 3.0 mol of gas occupying 0.075 m3^3. Compute the molar volume in m3^3/mol, to three decimal places.

Hints
  1. Molar volume is total volume divided by the number of moles.
  2. Compute 0.075 / 3.0.
Show the answer

0.025 (answers within ±0.001 count)

Why

v=V/n=0.075/3.0=0.025v = V/n = 0.075/3.0 = 0.025 m3^3/mol. Dividing one extensive quantity by another gives an intensive one, which describes the substance rather than the size of the sample.
