An object has a density of 1.8 g/mL and a mass of 14 g. What is the volume of the object

0.13 cm^3

Explanation:

Volume = Mass/ density

1.8 g/ml / 14g = 0.128571429

Both numbers have 2 significant digits.

With that, the answer rounds to 0.13

The final answer is 0.13 cm(don't forget the units for volume)

Hope it helped!
