Answer:
Since the mass is given in mg and the density in g/cm3, the first step is to convert one into compatible units. Let's convert the mass in mg into grams by dividing by 1000 (there is 1000 mg in 1 gram). So the mass is 0.035 g.
Since density = mass/volume, then volume = mass/density
So Volume = 0.035g/0.788 g/cm3 = 0.0444 cm3
