what is the density of an object that weigths 20g and displaces 2 litters of water?

Answer 1

The density is 20g divided by 2 liters. However, if you calculate it like that, you get 10g/liter, which is incorrect, because the universally accepted standard for expressing density is in the form of g/milliliter. So your answer would be 20g/2000mL, or, 0.01 g/mL.

Answer 2

Density = mass / volume
D = m / v

If the mass of an object is 20 grams and it displaces 2 Liters of water,
Density = 20 grams / 2 Liters
Density = 10 grams per Liter = 10 g/L

*mass and weight are not the same thing,
The gram is a unit of mass, the SI unit of weight is the Netwon,
1 N = 1 kg m/s^2.


EDIT:
If the units in the question are in grams and Liters, I would advise leaving the units in the answer in grams per Liter.

In actuality, the SI unit for density is kilograms per cubic meter, kg/m^3, not g/mL.

EDIT 2:
Areogel is said to have a density of .003 g/cm^3,
the material asked about in this question has a density over 3 times that of areogel, so it is indeed possible for a solid to have such a density.

Answer 3

Density=Mass/Volume

given: 20g and 2L or 2000mL

D=20g/2L
=10g/L

or

D=20g/2000mL
=0.01g/mL

Answer 4

d=w/v
=20 g/2000 mL
=0.01 g/mL
so light i think there are no such solid

Answer 5

0.01 gms per ml

Answer 6

10 g/L or 0.01 g/mL
