- 40.0 mL lead(II) nitrate solution, Pb(NO3)2(aq): mass = 44.0 g, clear/colorless, 20.0°C
- 40.0 mL potassium iodide solution, KI(aq): mass = 43.5 g, clear/colorless, 20.0°C
- Total mass before: 87.5 g
After mixing and filtering:
- Yellow solid collected (dried): mass = 3.6 g
- Filtrate (remaining liquid): mass = 83.9 g, clear/colorless
- Total mass after (solid + filtrate): 87.5 g
