Answer:

V2 = 0.998L

v2 = 0.000998mL

Explanation:

P1 = 392mmHg

V1 = 690mL

T1 = -15.1°C = 257.9k

P2 = 0.700atm = 532mmHg

V2 = ?

T2 = 233°C = 506K

using general gas equation

P1V1/T1 = P2V2/T2

(392 x 690.0 x 10^-³)/257.9 =(532 x V2)/506

1.05=(532 x V2)/506

1.05 x 506 =(532 x V2)

531.3 =(532 x V2)

V2 = 531.3/532

V2 = 0.998L

v2 = 0.000998mL

Osmotic pressure Π is given by the relation:Π = iMRTwhere i is the van’t Hoff factor, M is the concentration of solute, R is the

lions [1.4K]

Answer: The concentration of solute is 0.503 mol/L

Explanation:

To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

$\pi=icRT$

where,

$\pi$ = osmotic pressure of the solution = 24 atm

i = Van't hoff factor = 2 (for NaCl)

c = concentration of solute = ?

R = Gas constant = $0.08\text{ L atm }mol^{-1}K^{-1}$

T = temperature of the solution = $25^oC=[273+25]=298K$

Putting values in above equation, we get:

$24atm=2\times c\times 0.08\text{ L.atm }mol^{-1}K^{-1}\times 298K\\\\c=0.503mol/L$

Hence, the concentration of solute is 0.503 mol/L
