Once the sodium chloride has dissolved completely (swirl the flask gently if necessary), add water to bring the volume up to the final 100 ml. â¢Graduated Cylinder â¢Triple Beam Balance â¢Metal Cylinder â¢Wood Cylinder â¢Ruler, Meter stick, or Vernier Calipers ... S is a unit-less quantity, since the units of the densities cancel. Demonstrate the correct method of using beakers and graduated cylinders to determine the volume of solid objects using the water displacement method. Carefully level the powder without compacting, if necessary, and read the unsettled apparent volume (V 0) to the nearest graduated unit. The unit for volume is a unit derived from the SI unit of length and is not a fundamental SI measurement. What is the density of hexane? Use the mass and volume of the water to calculate density. 2.
