Lack of Informations?

Chemistry Level 2

Thai is doing an experiment about crystallization. He has a saturated \(\ce{KNO_3}\) solution in the beaker. As he waits for the water to evaporate, he falls asleep and forgot to measure the original mass of the solution! However, he knows the mass of water evaporated is \(40\text{ g}\). So, does he have enough information to calculate the mass of crystal separated out from the solution? If yes, what is the mass of crystal in grams? If not, write your answer as 0.

Details: The solubility of \(\ce{KNO_3}\) is \(35\text{ g}/100\text{ g}\) water at that temperature.
