Chemistry

$8.314\ \text{m}^3\text{Pa/mol K}$

Explanation:

Let us find the unit of the gas constant R from the ideal gas equation. We substitute the units of the quantities rearrange them and get the units of the gas constant.

P = Pressure = Pa

V = Volume = $\text{m}^3$

n = Moles = mol

T = Temperature = K

$PV=nRT\\\Rightarrow R=\dfrac{PV}{nT}\\\Rightarrow R=\dfrac{\text{Pa m}^3}{\text{mol K}}$

Here, $\text{Pa}$ is used so the gas constant value that must be used is $8.314\ \text{m}^3\text{Pa/mol K}$ .
