1. Mass / Volume (Remember the "Heart Shape")
2. Triple Beam Balance
3. grams
4. Graduated Cylinder (Irregular) / Ruler (LxWxH)
5. liters
6. More (Water = 1.0 g/ml); Sink
7. 15g / 10 cm3 = 1.5 g/cm3 (Sink)
8. 2.5 g / 1.7 ml = 1.47 g/ml (Sink)
9. 2.5g / 7.5 cm3 = .33 g/cm3 (Float)
10. 2.9g / 1.8 cm3 = 1.6 g/cm3 (Sink)
11. C = (.95 g/cm3); The ball is very close to suspending (Neutral bouyant) but is still slightly floating.
