Acertain ionic compound x has a solubility in water of 40.3 g/l at 20. degrees c. calculate the mass x of required to prepare 500. ml of a saturated solution of x in water at this temperature. be sure your answer has the correct unit symbol and 3 significant digits.

20.1 g

Explanation:

The solubility indicates how much of the solute the solvent can dissolve. A solution is saturated when the solvent dissolved the maximum that it can do, so, if more solute is added, it will precipitate. The solubility varies with the temperature. Generally, it increases when the temperature increases.

So, if the solubility is 40.3 g/L, and the volume is 500 mL = 0.5 L, the mass of the solute is:

40.3 g/L = m/V

40.3 g/L = m/0.5L

m = 40.3 g/L * 0.5L

m = 20.1 g

atomic number of carbon is 6
