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

1) Volume of water displaced = 5.16 L

2) Copper sinks in water.

Step-by-step explanation:

1) Density of copper = 8.92
`g/cm^3`

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
`cm^3`

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

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