Other equations of state may be used, such as the van der Waals equation of state, that takes into account the finite size of the atoms or molecules making up the gas, and the intermolecular forces between nearby molecules:

We could have measured the mass of the graduated cylinder instead; however, the graduated cylinder has a higher mass (getting close to the maximum of the analytical balance) and an awkward shape for use in the balance.
