Crude oil pumped out of the ground may be accompanied by the formation of water, a solution that contains high concentrations of NaCl and other salts.  If a boiling point of a sample of the formation of water is 2.0 Celsius above the boiling point of pure water, what is the molality of particles in the sample?

What and how??  Thank you guys for being here.

I have worked problems like this but when I get into this one I feel as though I am missing information and dont have enough to move forward in my calculations.

You need the ebullioscopic constant of water to solve this question.
