If 5wt% of silver nitrate solution is required, determine how many grams of silver nitrate is

need for an aqueous solution of 100ml.

What's the density of this 100 mL of SOLUTION? I don't know and can't answer the question without it.
5% w/w means 5 g AgNO3 in 100 g solution. IF you assume the density of this 100 mL is 1.00 g/mL, then the 100 mL will have a mass of 100 g. So you would need 5 g AgNO3 and 95 g H2O to make 5 g AgNO3/100 g solution which is 5 g AgNO3/100 mL if the density is 1.0 g/mL.
