In order to calculate the mass of #"18.2 mL"# of silver you must know its density, which is listed at #"10.49 g/cm"^3#.

#"18.2 mL" * ("1.0 cm"^3)/("1.0 mL") * ("10.49 g")/("1 cm"^3) = "190.9 g" = "191 g"#

So, what you basically have to do is implement the

#m = rho * V#

formula using conversion factors. Notice that the density is given in #"g/cm"^3#, 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.
