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.

Correct Answers B, B,C,D. Although I have reservations about answering this online. Unless your under 12 years old and not doing your homework reading, you should then be asking yourself why you can't answer such simple questions.

I agree -- b, b, c, d. And I also agree that it's silly that you can't answer these on your own. The only one that's remotely "tricky" is number 3, the difference between an internship and an apprenticeship.

whilst i'm out finding out to purchase and that i see somebody i locate eye-catching, I first, get the girls popped and arranged, mutually as I b) Undress him and picture what he's like in mattress then c) provide an prolonged, no longer consumer-friendly 2d look as I run into the reveal that's my thank you to d) Make the 1st flow and locate an excuse to communicate to him/her as a real gent will consistently help a woman who's bent over in a mini skirt to p.c.. up her spilled products... produce is my well-liked branch for choosing up interior the grocery, melons, cucumbers, cummtwats, and bananas are only so organic for beginning up conversations.

There is not a function that fits this pattern so false. b. false Given f(x) = -2x+3 evaluate f(-4) f(-4) = (-2 * -4) + 3 = 11 c. 11 Given f(x) = 2x + 1 and g(x) = -3x find f(g(x)) f(g(x)) = 2(-3x) + 1 = -6x + 1 b. -6x +1 Given f(x) = 4x and g(x) = x squared evaluate f(g(3)) f(g(x)) = 4x² f(g(3)) = 36 b. 36 The function y = -3x +5 has a slope True, it's slope is -3 a. true The function y = 2x-1 has a y intercept of -1 True, when x = 0, y = -1. a.true Determine the x intercept for the function 3x - 2y=9 When y = 0, 3x = 9, so x = 3 b. (3,0) The graph of y<-3x+5 would be a dashed line with shading below the line True. < would be a dashed line because there is no 'or equal to' part, and because it is 'less than' it is below the line. a. true (-1,3) is a solution to the system 4x - 2y = -10 and 2x + 5y = -7 Checking both equations (4 * -1) - (2 * -3) = -10 (2 * -1) + (5 * 3) = 13 The second equation does not work, so false. b. false Which of the following is the value of x in the system 3x - 5y = -1 and 6x+3y = 15 This is not a true or false question! Solve the system y = 4x - 1 and 3x - y = -2 Substitute equation 1 into 2 to find x 3x - 4x + 1 = -2 -x = -3 x = 3 y = 11 d. (3,11) Solve the system x - 7y = 2 and 2x - 14y = 4 These are actually the same equation. If you multiply both sides of the first by 2 then you get the second. That means there are an infinite number of solutions. a. an infinite number of solutions 1/2 x - 3 = 3/2 x +2 Multiply both sides by 2 x - 6 = 3x + 4 -2x = 10 x = -5 d. x = -5

1) 8x-4-4x = 2x-6 4x-4=2x-6 2x-4=-6 2x=-2 X=-1 Sorry, this was the only one i could do.
