Answer 1

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  `(pV^2T^2)/n` is given by

`= ((Nm^(-2))(m^3)^2(K)^2)/"mol"`

`= Mn^4K^2 mol^(-1)`

 

Answer 2

`((Nm^(-2))(m^3)^2(K)^2)/"mol" =  Nm^4 K^2 mol^(-1)`
