Ответ:
Molarity = 0.154 M
Explanation:
Given data:
Volume of solution = 8.42 × 10² mL ( 8.42 × 10² /1000 = 0.842 L)
Mass of potassium iodide = 22.4 g
Molarity of solution = ?
Solution:
Number of moles of potassium iodide:
Number of moles = mass/molar mass
Number of moles = 22.4 g/ 166.0 g/mol
Number of moles = 0.13 mol
Molarity:
Molarity = number of moles / volume in L
Molarity = 0.13 mol / 0.842 L
Molarity = 0.154 M
