Answer:

Molarity = 0.27 M

Explanation:

Given data:

Volume of solution = 820 mL (820/1000 = 0.82L)

Mass of KI = 36.52 g

Molarity of solution = ?

Solution:

Number of moles of KI:

Number of moles = mass/molar mass

Number of moles = 36.52 g/ 166 g/mol

Number of moles = 0.22 mol

Molarity = number of moles / volume in L

Molarity = 0.22 mol / 0.82 L

Molarity = 0.27 M
