Silver nitrite, AgNO2 (47.8 mg), was dissolved in water to make 10.00 mL of solution. Then 3.00 mL of that solution was used to make a new solution with a total volume of 1.000 L. What was the concentration of the silver ion in the final solution?

Calculate how many mL of the 5% w/v AgNO3* solution must be added to 0.4020g of the sample to precipitate all the chloride. Assume the sample is NaCl. * this means tat there are 5 grams of silver nitrate present per 100ml of solution.
