Question

If an object has a volume of 2.5 mL and a mass of 10 g, what is the density of the object?

Answer 1

The answer is 4                                                                                                                                                                                                                                 

done

Answer 2

We know, density = mass /volume 
Here, m = 10 g
v = 2.5 mL = 2.5 cm³

Substitute their values, 
density = 10/2.5
d = 4 g/cm³

In short, Your Answer would be 4 g/cm³

Hope this helps!
