The mass of silver nitrate (agNO3) required to prepare 400g of 3.50% solution = 14 grams calculation

mass % = mass of the solute / mass of the solvent

let mass of the solute = y

mass of solvent = 400g

%mass = 3.50 % into fraction = 3.5/100

=3.5/100 = y/400

multiply both side by 400

y = 14 grams
