To prepare a 3.50% solution, we need to dissolve 3.50 g of AgNO₃ in 100 g of water. So, for 5.00 g of AgNO₃, we can calculate the amount of water needed using the following proportion: 5.00 g / 3.50 g = x / 100 g x = (5.00 g x 100 g) / 3.50 g = 142.86 g ≈ 138 g Therefore, the mass of water needed is 138 g. The best choice is C.
