Wash the root in water. If the growing mix is difficult to remove from the fibrous roots then these should be removed. All water should evaporate from both root and shoot within 24-48 hours leaving a constant dry mass. Then calculate the average mass of a shoot in this group. Repeat the procedure with the shoots and roots from other groups.
