Determining the Density of a Solid using a Spring Balance Measuring Cylinder

1. Introduction:
Determining the density of a solid is an important scientific procedure that involves measuring the mass and volume of the object. In this case, we will use a spring balance measuring cylinder to determine the density of a solid that is denser than water. The density of a substance is defined as its mass per unit volume.

2. Materials Required:
To carry out this procedure, the following materials are required:
- Solid object (denser than water)
- Spring balance
- Measuring cylinder
- Water
- Stopwatch or timer
- Calculator

3. Procedure:
Follow these steps to determine the density of the solid:

Step 1: Measure the mass of the solid
- Start by measuring the mass of the solid using a spring balance.
- Attach the solid object to the spring balance and suspend it in the air.
- Record the mass of the solid in grams. Let's denote this as "m1".

Step 2: Measure the volume of water displaced
- Fill a measuring cylinder with water up to a certain level.
- Note the initial volume of water in the measuring cylinder. Let's denote this as "V1".
- Gently lower the solid object into the measuring cylinder, ensuring it is fully submerged.
- The water level will rise due to the displacement caused by the solid object.
- Note the final volume of water in the measuring cylinder. Let's denote this as "V2".

Step 3: Calculate the volume of the solid
- Subtract the initial volume (V1) from the final volume (V2) to determine the volume of water displaced by the solid object. Let's denote this as "V".
- Convert the volume of water displaced from milliliters to cubic centimeters (1 mL = 1 cm^3).

Step 4: Calculate the density of the solid
- Divide the mass of the solid (m1) by the volume of the solid (V) to obtain the density of the solid.
- The density can be calculated using the formula: Density = mass/volume.

4. Conclusion:
By following the above procedure and calculations, you can determine the density of a solid that is denser than water using a spring balance measuring cylinder. It is important to record accurate measurements to obtain precise results. The density of the solid will be expressed in grams per cubic centimeter (g/cm^3).
