You would dissolve 8.75 g of #"AgNO"_3# in enough water to make a total of 250.0 mL.

Explanation:

3.50 % m/v means that there are 3.50 g of solute in 100 mL of solution.

Thus,

#"Mass of AgNO"_3 = 250.0 color(red)(cancel(color(black)("mL solution"))) × ("3.50 g AgNO"_3)/(100 color(red)(cancel(color(black)("mL solution")))) = "8.75 g AgNO"_3#
