Sagot :
The concentration or Molarity of bromide ion in the sample solution is 0.077 M.
What is molarity ?
- A substance's molarity (M) is the volume of solution in which it is present.
- The amount of a solute in moles per liter of a solution is known as molarity.
- A solution's molar concentration is another name for molarity.
- The secret to determining molarity is to keep in mind that it is measured in moles per liter (M).
- Molarity is determined by:
- Count the moles of solute dissolved in the solution.
- Calculate the solution's volume in liters, and.
- Divide liters of solution by moles of the solute.
In the given question,
0.361 g AgBr × (1 mol AgBr/187.77 g AgBr) × (1 mol Br⁻/1 mol AgBr) × (80.0 g Br⁻/1 mol Br⁻) = 0.1536 g Br⁻
0.1536 × (1 mol Br⁻/80.0 g Br⁻) = 0.00192 mol
Molarity = 0.00192 mol/0.025 L = 0.077 M
