Question

The weight of each agno3 required to prepare 250ml of a solution containing 50 mg of agno3 per ml will be

Answer 1

We are given: Concentration of silver nitrate = 0.03 g/mL. We need to find the amount of silver nitrate that is present in 120 mL of solution. Using unitary method, we get: 1 mL of solution contains 0.03 grams of silver nitrate. Conversion factor used: 1 g = 1000 mg. Hence, the correct answer is Option 1.
