Question

3. Concentrations in solution. How many mL in 1 L? ____ If you dissolve 25 g of a chemical in 100 mL, what is the concentration of the solution in g per L? Concentration in solution in percent means grams per 100 mL. To make a 5.0% solution of a compound, how many g would you weight out if the final volume of solution was 250 mL? 4. Concentrations in solution. Molarity (M, number of mol per L). If the molecular weight of a compound is 240 g per mol, how many g would you weigh out to make 250 mL of a 1.0 M solution? If 500 mL of a 0.1 M solution contains 20 g of a compound, what is its molecular weight? 5. Dilutions. If you take 25 mL of a 500 ppb solution and add sufficient water until the volume is 100 mL, and mix thoroughly, what is the concentration of the final solution? You dilute 10.0 mL of a 2.50 M solution to 500 mL, what is the final concentration?
