<u>Answer:</u> The correct option is C) 1.68 mol/L
<u>Explanation:</u>
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:
.....(1)
Given values:
Given mass of
= 150 g
Molar mass of
= 180 g/mol
Volume of the solution = 0.50 L
Putting values in equation 1, we get:

Hence, the correct option is C) 1.68 mol/L
