Answer:
1.) density can be defined as the mass of the substance in unit volume
density=mass/volume
2.)2.70g/mL
mass of the block =146
length× width×height=54cm=54mL
density=mass/volume =146 g/54 mL =2.70 g/mL
3.) 3.39 g/mL
4.)Accepted value is the value that scientists and community accept as true. This is a theoretical value.
5.)Percent error is 9.11 % The element which has 7.13 g/cm³ as density is Zinc (Zn).

Answer:
Too much phosphorus in the water causes algae to grow faster than ecosystems can handle. Large growths of algae are called algal blooms and they can <u>severely reduce or eliminate oxygen in the water</u>, leading to illnesses in fish and the death of large numbers of fish.
Explanation
Futhermore, with a loss of fish the whole ecosystem will be upset and will be in need of serious recovery.
D. the can from the car because there are fewer solute-solvent collisions.
