## Title: Measurement of Coin Masses
### Aim
The aim of this experiment was to measure the masses of different coins (penny, nickel, and quarter) using a systematic approach to ensure accurate and consistent results.
### Objectives
1. To determine and record the mass of a single penny.
2. To determine and record the mass of a nickel using two coins.
3. To determine and record the mass of a quarter using three coins.
4. To compare the masses of different coins and understand their physical properties.
### Apparatus / Chemicals
- Analytical balance
- Single penny (1)
- Two nickels (2)
- Three quarters (3)
- Clean petri dish (for holding coins on the balance)
- Tweezers (to avoid contamination)
### Procedure
1. **Calibration of the Analytical Balance**: Ensure the analytical balance is calibrated and zeroed before beginning measurements.
2. **Mass of a Penny**:
- Place a single penny on the balance using tweezers.
- Record the mass displayed on the balance.
3. **Mass of a Nickel**:
- Place two nickels on the balance, ensuring that they do not touch any external surfaces.
- Record the mass displayed on the balance.
4. **Mass of a Quarter**:
- Place three quarters on the balance in a similar manner.
- Record the mass displayed on the balance.
5. **Repeat Measurements**: Each measurement is repeated three times for accuracy, and the average mass is calculated for final results.
### Observations
1. **Single Penny**: The single penny consistently showed a mass (average) of 4.78 g (4780 mg).
2. **Two Nickels**: The two nickels showed a consistent mass (average) of 13.77 g (13770 mg).
3. **Three Quarters**: The three quarters had an average mass of 31.77 g (31770 mg).
### Results
- **Mass of a Penny**: 4.78 g (4780 mg)
- **Mass of a Nickel (2 coins)**: 13.77 g (13770 mg)
- **Mass of a Quarter (3 coins)**: 31.77 g (31770 mg)
### Conclusions
The experiment successfully measured the masses of various coins using a systematic approach. The mass of a single penny was found to be 4.78 g, the mass of two nickels was 13.77 g, and the mass of three quarters was 31.77 g. The results illustrate that coins vary in mass due to their composition and design. Moreover, the methodology of using multiple coins to verify mass contributes to improved accuracy in measurement. This experiment reinforces the importance of precision in quantitative measurements in chemistry and material sciences.
Future experiments could further explore the relationship between the materials of the coins and their respective masses, as well as potential variations in mass over time due to wear and environmental factors.
