Yes.
1) Take a simple postal scale and measure the force it takes to lift the scoop at some reasonable distance from the pivot point.
2) Multiply that force by the distance from the pivot to get torque. Use a consistent system of units.
3) Compare that required torque to the torque rating of the servo.
