Question:

What would be the SI unit for the quantity pV²T ²/n?

Answer:

The SI unit of the given quantity is obtained by substituting the SI units of all the quantities in its expression.

Also

The SI unit for pressure, p is Nm^–2.

The SI unit for volume, V is m^3.

The SI unit for temperature, T is K.

The SI unit for the number of moles, n is mol.

Therefore, the SI unit for quantity pV²T² / n is given by substituting the above values in the given expression

pV²T² / n = (Nm^-2) x (m³)² x K²/ mol

= Nm⁴K² mol^-1
