To find the critical constants of HCl using the given Van der Waals constants \( a \) and \( b \), we will follow these steps: ### Step 1: Convert the value of \( b \) from cm³/mol to dm³/mol The given value of \( b \) is \( 40.8 \, \text{cm}^3/\text{mol} \). We need to convert this to dm³/mol: \[ b = 40.8 \, \text{cm}^3/\text{mol} \times \frac{1 \, \text{dm}^3}{1000 \, \text{cm}^3} = 0.0408 \, \text{dm}^3/\text{mol} \] ...
