Calculate the mass of silver nitrate needed to prepare a solution of concentration 0.01 moles per litre
I can't answer this without knowing how much of the solution you wish to prepare.
If you want it to be 0.01M and you want, say, 500 mL, then
moles needed = M x L = 0.01M x 0.5L = 0.005 moles.
Then moles = grams/molar mass and solve for grams.
