Question

Silver dissolves in molten lead. Compute the osmotic
pressure of a 0.010 m solution of silver in lead at 423°C.
Compute the height of a column of molten lead (D=11.4 g cm -3) to which this pressure corresponds.

Answer 1

@70vebelle could you help me out ?

Answer 2

first use the osmotic pressure formula :
We calculate the osmotic pressure, The symbol for pi (pi), using the following equation:
Pi = MRT
M is the molar concentration of dissolved species.
R is the ideal gas constant (0.08206 L atm mol-1 K-1, or other values depending on the pressure units).
T is the temperature on the Kelvin scale.

Pi = 0.010M * (0.082057L-atm/mol-K) * (423+273)K
Pi = 0.571 atm

To find hight we have to use
Pressure = height*density*gravity
Height = pressure/ (desity*gravity)
Here you need to convert units into SI system
Convert .571 atm to SI unit for pressure
P = 0.571atm*101325Pa/atm= 57868 Pascals
Convert SI unit for density
d = 11.4g/cm3*(1kg/1000g)(100cm/1m)^3 = 11400 kg/m3

g is in SI unit = 9.81kgm/s^2
Now you are ready to find height
h = 57858 Pa /(11400 kg/m3 * 9.81kgm/s2) = 0.518 m of lead.
