To accurately measure the density of a series of small irregular solids made of plastic, wood, fibreglass, and glass, a student will need which of the following laboratory tools?<\/p>\n\n\n\n

A.

B.

The correct answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer is A. Graduated cylinder, water, weighing balance<\/strong>.<\/p>\n\n\n\n

To measure the density of small irregular solids, the student will need to follow a systematic approach. Density is defined as mass per unit volume, typically expressed in grams per cubic centimeter (g\/cm\u00b3). To determine the density of a solid object, two measurements are essential: its mass and its volume.<\/p>\n\n\n\n

    \n
  1. Weighing Balance<\/strong>: This tool is crucial for measuring the mass of the solid. The mass needs to be determined accurately, as any error in mass will directly affect the calculated density. A balance will provide precise measurements, typically in grams, which is necessary for our calculations.<\/li>\n\n\n\n
  2. Graduated Cylinder<\/strong>: This laboratory tool is used to measure the volume of water displaced by the irregular solid. Since the solid’s shape is irregular, traditional geometric volume calculations would be impractical. By submerging the solid in water, the volume of the water displaced can be measured using the graduated markings on the cylinder. The amount of water displaced equals the volume of the solid, according to Archimedes’ principle.<\/li>\n\n\n\n
  3. Water<\/strong>: Water serves as the medium for displacement. The density of the solid can be calculated using the formula: [
    \\text{Density} = \\frac{\\text{Mass}}{\\text{Volume}}
    ]<\/li>\n<\/ol>\n\n\n\n

    Once the mass of the solid is recorded using the weighing balance and the volume is determined by the displaced water in the graduated cylinder, the student can easily compute the density.<\/p>\n\n\n\n

    The other options (B, C, D) do not provide the necessary tools to accurately measure both mass and volume for calculating density. A spectrophotometer (B) measures light absorbance, which is irrelevant for density measurements; a graduated beaker and metric ruler (C) are not suitable for precise volume measurement of displaced water; and a Bunsen burner (D) is not required for this procedure. Thus, option A is the best choice.<\/p>\n","protected":false},"excerpt":{"rendered":"
