Understanding the Density of Liquids
Density is defined as the mass per unit volume of a substance. The formula for calculating density is:
Density (ρ) = Mass (m) / Volume (V)
Units: kg/m³ or g/cm³
where:
- Mass is measured in grams (g), and
- Volume is measured in milliliters (mL) or cubic centimeters (cm³).
The SI unit for density is grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
Materials Required
To conduct this experiment, we require the following materials:
- A graduated cylinder (100 mL capacity)
- Electronic balance (accuracy up to 0.01 g)
- Different liquid samples (e.g., water, alcohol, oil, glycerin)
- Dropper or pipette
- Beaker (for pouring liquids)
- Labeling stickers
- Tissue paper (for cleaning any spills)
Experimental Procedure
Step 1: Measuring the Mass of the Empty Cylinder
- Place a clean, dry graduated cylinder on the electronic balance.
- Record its mass in grams (M₁).
Step 2: Adding the Liquid Sample
- Pour approximately 50 mL of the selected liquid into the graduated cylinder.
- Carefully read and record the exact volume from the meniscus.
- Place the cylinder containing the liquid on the electronic balance and record the new mass (M₂).
Step 3: Calculating the Density of Liquids
- Determine the mass of the liquid using the formula: Mass of Liquid = M₂ – M₁
- Use the recorded volume (V) and apply the density formula: Density (M₂ – M₁)/(V)
- Record the density value for each liquid sample.
Step 4: Repeating for Accuracy
- Repeat the experiment three times for each liquid.
- Calculate the average density to reduce errors.
