In order to calculate the mass of 18.2 mL of silver you must know its density, which is listed at 10.49 g/cm3.

18.2 mL⋅1.0 cm31.0 mL⋅10.49 g1 cm3=190.9 g=191 g

So, what you basically have to do is implement the

m=ρ⋅V

formula using conversion factors. Notice that the density is given in g/cm3, which is equal to g/mL, like the second term suggests. The answer is rounded to three sig figs because that is the number of sig figs 18.2 has.
