Chapter 4 Concentration 1. What is the molarity of a solution in which 0.45 grams of sodium nitrate are dissolved in 265 mL of solution? 2. What will the volume of a 0.50 M solution be if it contains 25 grams of calcium hydroxide? 3. How many grams of ammonia (NH,) are present in 5.0 L of a 0.050 M solution? If I make a solution by adding water to 35 mL of methanol (CH,OH) until the final volume of the solution is 275 mL, what is the molarity of methanol in this solution? (The density of methanol is 0.792 g/mL) 4. Dilution
