Answer: M = 0.01 M C12H22O16

Explanation: First convert the mass of C12H22O16 into moles using the molar mass of the compound.

5 g C12H22O16 x 1 mole C12H22O16 / 342 g C12H22O16

= 0.01 mole C12H22O16

To calculate the molarity we will use the following formula.

M = n / L

= 0.01 mole / 1 L

= 0.01 M C12H22O16
