General Chemistry II Problem Set, Please Help
The following pairs of aqueous solutions are separated by a semipermeable membrane. In which direction will the solvent flow? A= 1.25 M NaCI; B = 1.45 MKCI A = 3.30 M CaCI2; B = 3.50 M NaBr A = 4.52 M glucose; B = 2.55 M NaCI Physiological Saline 100.0 mL of a solution of physiological saline (0.92% NaCl by weight) is diluted by the addition of 210.0 mL of water. What is the osmotic pressure of the final solution at 37CC? Assume that NaCI dissociates completely into Na+ and Cl-. Solid helium cannot be converted directly into the vapor phase. Does the phase diagram of He have a triple point? Choose the answer and the best explanation for that answer. No, helium is so light that it cannot exist as a liquid and a gas simultaneously; the liquid spontaneously converts to the gas phase. Yes, the triple point simply describes the conditions under which all three phases of matter coexist. Yes, all substances have a triple point, It is impossible to say without further information, No, without a sublimation curve there can be no triple point.Explanation / Answer
)
a)B to A
b)B to A
c)A to B
2)Pi = i*C*S*T
m = 0.92/58.5(1000/100)
m = 0.00157
Pi = 2*0.00157*0.0821*310K
Pi = 0.0799 atm or 0.08 atm
3) first option is correct
