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??

Answer:

1) Volume of water displaced = 5.16 L

2) Copper sinks in water.

Explanation:

1)  Density of copper = 8.92[tex]g/cm^3[/tex]

 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 [tex]cm^3[/tex]

  Since the density of copper 8.92[tex]g/cm^3[/tex] is greater than density of water 1[tex]g/cm^3[/tex], 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 [tex]cm^3[/tex] =5.16 L of water

2)  Since the density of copper 8.92[tex]g/cm^3[/tex] is greater than density of water 1[tex]g/cm^3[/tex], the copper immerses in water.  So copper sink in water.
