The SI generally uses its base units to compute constants involving derived units. The SI unit for volume, for example, is the cubic meter, called the stere, because the meter is the base unit of length. We learned about the SI unit of pressure, the pascal, in this chapter. The temperature unit is the kelvin. Calculate the value of the gas constant in the SI units, $\mathrm{m}^{3} \mathrm{~Pa} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$.
