This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &...

    DENSITY AND SPECIFIC GRAVITY Materials and Methods Part 1: Density of an Unknown Solid 1. We first were asked from our laboratory instructor to attain an unknown solid and were asked to note down the number of the solid. 2. Determine the mass of the unknown solid to the nearest 0.001 g and record it in the data table in the back of the laboratory workbook. 3. Then we determined the volume of the unknown solid by water displacement. We first filled a 100mL graduated cylinder about...
