What would be the osmotic pressure of 0.05 M solution of sucorse at `5^(@)C` ? Find out the concentration of a solution of glucose which would be isotonic with this solution of sucrose. (Molecular mass of sucrose = 342, Molecular mass of glucose = 180)

Explanation

P=CRT
`P=0.05xx0.082xx278 atm`
Concentration of sucrose solution is 0.05 N or `0.05xx342 g=17.1 g//L`
Isotonic solutions have same osmotic pressure
`pi_("sugar")=pi_("glucose")`
`C_("sugar")=C_("glucose")`
`(17.1)/(342)=(x)/(180)`
`x=9g//L`
