Question

Calculate the mass of sugar that can be dissolved in 300 ml of solution to make it to 50%

Answer 1

Answer:

Given: Wt. of solute (w)=1.71g

Molar mass of solute (m)=342

Volume of solution (v)=500ml=0.5lt

Temperature (T)=300K

Gas constant (R)=0.0821ltatmK

wRT

=

342×0.5

1.71×0.0821×300

=0.25atm

Thus, Osmotic pressure of the solution is 0.25atm.
