What is the volume of an object that has a density of 2.73 g/mL and a mass of 4.002 g

Question

Please include significant figures! and the unit! 

Answer 1

Density = Mass/Volume  as you can see from the units g/mL...grams (a unit of mass) per milliliter (a unit of volume)

So Volume=Mass/Density    = 4.002g/2.73g/mL=1.47mL (3 sig. fig.)
