Water Container (Substance). This element measures the solubility of a substance. You can only place a lump of a substance scooped by the mass scooper in the Water Container. You can either use the mass scooper to place the scoop directly in the Container, or you can use the Select tool to move the mass scoop substance (pile or scoop) into the Container (Fig. 1). You can place as much of the substance in the container as you wish. The display indicates how much of the substance has dissolved in the water (Fig. 2). A lump of substance (note the location of the cursor in Fig. 2) indicates the undissolved substance. To determine the mass of the undissolved substance, open the Properties Box of the lump.
