Question
A certain organic compound O has a solubility in acetonitrile of 0.792gmL at 15.°C. Calculate the greatest mass of O that could be dissolved in 700.mL of acetonitrile at this temperature. You may assume the volume of the solution doesn't change as the O is dissolved.Be sure your answer has the correct unit symbol and number of significant digits.
Solution
The solubility of the organic compound O in acetonitrile is given as 0.792 g/mL. This means that 1 mL of acetonitrile can dissolve 0.792 g of the compound O at 15°C.
To find out the greatest mass of O that could be dissolved in 700 mL of acetonitrile, we simply multiply the volume of acetonitrile by the solubility of the compound O.
So, the calculation would be:
0.792 g/mL * 700 mL = 554.4 g
Therefore, the greatest mass of O that could be dissolved in 700 mL of acetonitrile at 15°C is 554.4 g.
