1. an object has a mass of 10g and a volume of 50ml. what is the density?
explain and show your work

2. an object has a density of 2 g/ml and a mass of 20g. what is the volume?
explain and show your work.

1. 0.2 g/mL

The relationship between mass, density and volume of an object is

where

d is the density

m is the mass

V is the volume

For the object in this problem, we have

m = 10 g

V = 50 mL

Substituting into the equation,

2. 10 mL

In this exercise we know:

- The density of the object: d = 2 g/mL

- The mass of the object: m = 20 g

Therefore, we can re-arrange the previous equation to find the volume:

And substituting values into the equation, we find

the inner core.
