<u>Answer:</u>
<u>For A:</u> The molarity of solution is 0.218 M.
<u>For B:</u> The molarity of solution is 0.532 M.
<u>For C:</u> The molarity of solution is
<u>Explanation:</u>
Molarity is defined as the number of moles present in one liter of solution.
Mathematically,
Or,
- <u>For A:</u> 0.12 mol of in 5.5 L of solution
We are given:
Moles of = 0.12 moles
Volume of the solution = 5.5 L
Putting values in above equation, we get:
Hence, the molarity of solution is 0.0218 M.
- <u>For B:</u> 60.7 g in 2.48 L of solution
We are given:
Given mass of = 60.7 g
Molar mass of = 46 g/mol
Volume of the solution = 2.48 L
Putting values in above equation, we get:
Hence, the molarity of solution is 0.532 M.
- <u>For C:</u> 14.2 mg KI in 100 mL of solution
We are given:
Given mass of KI = 14.2 mg = (Conversion factor:
Molar mass of KI = 166 g/mol
Volume of the solution = 100 L
Putting values in above equation, we get:
Hence, the molarity of solution is
