Question
The solubility in acetonitrile of organic compound O is measured and found to be 0.343gmL at 15.°C. Calculate the volume of a saturated solution of O in acetonitrile that would contain 170.mg of O at this temperature.Be sure your answer has the correct unit symbol and number of significant digits.
Solution
To solve this problem, we need to convert the mass of compound O from milligrams to grams, and then use the solubility of compound O in acetonitrile to find the volume of the solution.
-
Convert the mass of compound O from milligrams to grams: 170 mg = 0.170 g
-
Use the solubility of compound O in acetonitrile to find the volume of the solution: Solubility = mass/volume Therefore, volume = mass/solubility Volume = 0.170 g / 0.343 g/mL = 0.496 mL
So, the volume of a saturated solution of O in acetonitrile that would contain 170 mg of O at 15°C is approximately 0.496 mL.
