Sample Calculations:
- Average Mass of Kidneybeanium: 1660.00 mg/3= 553.33 mg
- Average Mass of Pintobeanium: 2830.00 mg/6= 471.67 mg
- Average Mass of Blackeyedpeaium: 1110.00 mg/5= 222.00 mg

- Relative Abundance of Kidneybeanium: 3/14= 0.2143
- Relative Abundance of Pintobeanium: 6/14= 0.4286
- Relative Abundance of Blackeyedpeaium: 5/14= 0.3571

- Relative Weight of Kidneybeanium: 553.33 mg x 0.2143 = 118.58
- Relative Weight of Pintobeanium: 471.67 mg x 0.4286 = 202.16
- Relative Weight of Blackeyedpeaium: 222.00 mg x 0.3571 = 79.28
