First I calculated the NaCl grams in a liter of solution, so for 0.1% I have 0.01g of NaCl. Then I divided by the 58.44 (MW) to get moles. Then I divided the moles by 1 liter (since the osmolality is per 1 kg of solution) to get the molality. Then I multiplied the molality by the dissociation constant of NaCl (1.8). Then I divided by 1000 to get mOsm.

The final answer I got is 0.308008214 mOsm/kg. Can someone double check my math?

Thanks
