Question
A certain ionic compound X has a solubility in water of 24.4gL at 5.°C. Calculate the mass of X required to prepare 2.0L of a saturated solution of X in water 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 understand that solubility is the maximum amount of a substance that can dissolve in a certain amount of solvent at a specified temperature. In this case, the solubility of compound X in water is given as 24.4 g/L at 5°C.
Step 1: Identify the given values
- Solubility of X = 24.4 g/L
- Volume of the solution = 2.0 L
Step 2: Use the solubility to calculate the mass of X The solubility of X is given in g/L, so we can calculate the mass of X needed for a 2.0 L solution by multiplying the solubility by the volume:
Mass of X = Solubility of X * Volume of the solution = 24.4 g/L * 2.0 L = 48.8 g
So, you would need 48.8 g of compound X to prepare 2.0 L of a saturated solution at 5°C. The answer has the correct unit (g) and the correct number of significant digits (three).
