Question: 16. What is the molality of a solution prepared by dissolving 35 g NaCl in 250 g water? 2.40 m 2.40 M 0.00240 m 17. What is the molality of a solution of 30 g KCl dissolved in 100 kg water? 0.402 m 0.0402 m 0.00402 m 18. What is the mole fraction of 18 mol NaCl in a solution of 100 mol water? 0.15 0.18 0.18 X 19. What is the mole fraction of 50 g Cl2 dissolved in a 100,000 liter pool? (Hint: 1 liter of water can be approximated as 1 kg of water) 0.00025 X 0.000014 1.28 x 10-7 20. raising the temperature of a liquid solution when the solute is a gas increase decrease remain the same 21. raising the temperature of a liquid solution, if the temperature remains constant when a solid solute is mixed with the solvent increase decrease remain the same 22. raising the temperature of a liquid solution, if the temperature rises when a solid solute is mixed with the solvent increase decrease remain the same 23. raising the temperature of a liquid solution, if the temperature drops when a solid solute is mixed with the solvent increase decrease remain the same

No. Not really. These and your other posts look remarkably like a boatload of homework problems that you are too lazy to do and want someone else to do for you. We're quite fine with helping you understand some sticky point of chemistry, but not with doing your work for you. For instance, if you didn't know what "molarity" is, we would be glad to explain that molarity is the ratio of the moles of solute to the volume of solution.

When I am out shopping and I see someone I find attractive, I first, get the girls popped and ready, while I b) Undress him and imagine what he is like in bed then c) Give a long, hard second glance as I run into the display which is my way to d) Make the first move and find an excuse to speak to him/her as a true gent will always help a woman who is bent over in a mini skirt to pick up her spilled items... produce is my favorite department for picking up in the grocery, melons, cucumbers, cummtwats, and bananas are just so natural for opening conversations.
