## Shido88 2 years ago When 4.45 g of a nonelectrolyte solute is dissolved in 945 mL of water at 21 °C, the resulting solution exerts an osmotic pressure of 845 torr.

1. Shido88

1) What is the molar concentration of the solution? 2)How many moles of solute are in the solution? 3)What is the molar mass of the solute?

@saifoo.khan here

3. Shido88

i am stuck dude.... :(

4. saifoo.khan

Sorry. I can't solve this. :/

29. Shido88

so don't lieee!! lol

30. Shido88

well u get to nap whenever u want to so i guess yeah? lol

31. Shido88

can you rank freezing point from high to low saif ?

32. Shido88

wanna try? :)

33. saifoo.khan

Lol. No. Education there is easy. It's hard here. Not lying. Sure. throw the question

34. Shido88

Assuming equal concentrations, rank these aqueous solutions by their freezing point. Highest to Lowest. Sn(NO3)4 NH4CL AlBr3 Na2CO3

35. Shido88

have fun :)

36. Shido88

oh yeah and 1 more thing, watch out for polyatomic ions.

37. Shido88

need a red bull? XD

38. saifoo.khan

Sorry someone was on the door.

39. saifoo.khan

No man. Can't solve this either. Try googling their freezing points.

40. Shido88

saiffffffffff!!!! wat is wrong with u today?

41. Shido88

WTF <---- lol

42. Shido88

jk lol u need to go into chem asap

43. saifoo.khan
