Answer:
20 g/ml.
Step-by-step explanation:
To calculate the density of the object, we need to divide its mass by its volume.
Density = Mass / Volume
we have
mass =3000g
volume=150 ml
Now we can calculate the density:
Density = 3000g / 150 L
Density = 20 g/ml
Therefore, the density of the object is 20 g/ml.
