Question

calculate the osmotic pressure 6% sucrose solution.

Answer 1

Osmotic presuure=i*C*R*T,
where, C=concentration of solute(in terms of Molarity)
R= Gas constant=0.082 L(atm)(mol)-1K-1
T=temperature (in Kelvin)
i=Van’t-Hoff factor(=1 for non-electrolyte)
6% sucrose solution means 6g sucrose is present in 100ml of solution.

mole of sucrose =weight given/Molecular weight of sucrose

Hence Concentration(C) of sucrose (in terms of Molarity)
= (mole of sucrose (n)/Volume of solution)
