    Answer: The correct option is C) 1.68 mol/L

    Explanation:

    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:

    \text{Molarity of solution}=\frac{\text{Given mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (L)}} …..(1)

    Given values:

    Given mass of C_6H_{12}O_6 = 150 g

    Molar mass of C_6H_{12}O_6 = 180 g/mol

    Volume of the solution = 0.50 L

    Putting values in equation 1, we get:

    \text{Molarity of solution}=\frac{150}{180\times 0.50}\\\\\text{Molarity of solution}=1.68M

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