The resistor in the Laplace space is equal to the value of the resistor in the time domain analysis. Also, inductance in Henry will be substituted with an impedance when its value is equal to its value which is multiplied by S in the Laplacian space. In addition, you can divide the capacitor value by S to convert the capacitor value from the time domain to Laplace space. Therefore, you have three series impedance in your example when the R=1ohm, L(S)=S, and the C(S)=1/S and you just need to sum up all parameters with each other.
