Answer:
Fist column, apply the density of water.
Second column is material density, so it's mass of sample / volume of sample
Step-by-step explanation:
Water density is 1 g/mL
Mass / Volume
If you have 0.25 g, 0.45g and 0.46 g of water, then you have the same values as volume, 0.25mL, 0.45mL and 0.46mL.
Again, density is the relation mass / volume so:
2.20 g / 0.25mL
3.73 g / 0.46 mL
3.52 g / 0.45mL
