If the osmotic pressure of a dilute solution is 7*10^5 at 273K then its osmotic pressure at 283 K is?
1 Answer
Umakant biswal
@ SONA
the formula for osmotic pressure is
pie= CRT
in which c is the concentration
R is the universal gas constant ,
and T is the tempreature .
acc to the questions
pie (1)= 7*10^5
t(1) = 273 k
from here u can calculate C(1) = 7*10^5 / 0.0821 * 273
then frame anathor equation
that is PIE (2) = C2R2T2
THEN PUT THE VALUE OF C in equation 2 and u already known the R= 0.0821
AND ALSO put T(2) = 283 K
and u will get the answer ..
hope it clears your doubt
