Show work 1) copper has density of 8.92 g/cm^3. how many milliliters of water would be displaced if 46kg of copper granules were poured into a barrel filled with water? 2) if the density of water is 1.00 g/ml, will the substances above float or sink in the water? ?

1) Volume of water displaced = 5.16 L

2) Copper sinks in water.

Explanation:

1)  Density of copper = 8.92

 Mass of copper = 46 kg = 46000 g

 We know that, Density = Mass / volume

        So, Volume = Mass/ density

              Volume of copper = 46000/8.92 = 5156.95

  Since the density of copper 8.92 is greater than density of water 1, the copper immerses in water. Since it immerses it will displace a volume of water which is equal to the volume of copper.

  So volume of water displaced = volume of copper = 5156.95 =5.16 L of water

2)  Since the density of copper 8.92 is greater than density of water 1, the copper immerses in water.  So copper sink in water.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
