To solve for the solubility of CuBr in pure water and in a $$ 0.0110 \, \text{M} \, \text{CoBr}_{2} $$ solution, we need to follow these steps:

1. **Find the $$ K_{sp} $$ value for CuBr**: This value is typically provided in the data tab. Let's denote it as $$ K_{sp} $$.

2. **Set up the solubility equilibrium expression**:
   $$
   \text{CuBr (s)} \rightleftharpoons \text{Cu}^+ (aq) + \text{Br}^- (aq)
   $$
   The solubility product constant expression is:
   $$
   K_{sp} = [\text{Cu}^+][\text{Br}^-]
   $$

3. **Calculate the solubility in pure water**:
   Let $$ s $$ be the solubility of CuBr in mol/L. Then:
   $$
   K_{sp} = s \cdot s = s^2
   $$
   Therefore, we can find $$ s $$ by rearranging:
   $$
   s = \sqrt{K_{sp}}
   $$

4. **Calculate the solubility in $$ 0.0110 \, \text{M} \, \text{CoBr}_{2} $$**:
   The dissociation of CoBr₂ gives:
   $$
   \text{CoBr}_{2} \rightleftharpoons \text{Co}^{2+} + 2\text{Br}^-
   $$
   The concentration of Br⁻ from CoBr₂ is $$ 2 \times 0.0110 \, \text{M} = 0.0220 \, \text{M} $$.

The equilibrium expression becomes:
   $$
   K_{sp} = [\text{Cu}^+][\text{Br}^-] = s \cdot (0.0220 + s) \approx s \cdot 0.0220 \quad (\text{assuming } s \text{ is small})
   $$
   Thus:
   $$
   K_{sp} = s \cdot 0.0220
   $$
   Rearranging gives:
   $$
   s = \frac{K_{sp}}{0.0220}
   $$

5. **Calculate both solubilities** and round to 2 significant digits.

Now, please provide the $$ K_{sp} $$ value for CuBr so I can perform the calculations.
To find the solubility of CuBr in pure water and in a $$ 0.0110 \, \text{M} \, \text{CoBr}_{2} $$ solution, follow these steps: 1. **Find the $$ K_{sp} $$ value for CuBr** from the ALEKS Data tab. 2. **Calculate solubility in pure water**: $$ s = \sqrt{K_{sp}} $$ Round to 2 significant digits. 3. **Calculate solubility in $$ 0.0110 \, \text{M} \, \text{CoBr}_{2} $$**: $$ s = \frac{K_{sp}}{0.0220} $$ Round to 2 significant digits. Provide the $$ K_{sp} $$ value to proceed with the calculations.
