Canvas Classes · Accepted Answer

Strategy:
 The overall dissociation constant () is the mathematical reciprocal of the overall formation/stability constant ().

Step 1: Formulate the relationship

Step 2: Execute calculation
Given .

.

Step 3: Extract 'y'
The formula takes the form .
Therefore, .
Rounding to the nearest integer gives 5.
