In cars, ethylene glycol, C2H6O2, is used as a coolant and antifreeze. If a mechanic fills a radiator with 6.5 kg of ethylene glycol and 1.5 kg of water, what is the molality of the water?

Molality is moles of solute divided by kg. of solvent.

In you case, the ethylene glycol is the solute. Divide the 6.5 kg by the molecular mass of the glycol and you have the moles.

Now divide the moles by 1.5 kg of water and you have the molality answer
