Question

An aqueous solution of sucrose,`C_(12) H_(2) O_(11)` containing 34.2 g/L has an osmotic pressure of 2.38 atmospheres at `70^(o) C. ` for an aquesous solution of glucose, `C_(6)H_(12)O_(6)` to be istonic with this solution ,it would have :
A. 34.2g/L
B. 17.1 g/L
C. 18.0 g/L
D. 36.0 g/L of glucose

Answer 1

Correct Answer - C
`34.2 g L ^(-1) "sucrose" = 0.1 M,`
`18 g L^(-1) "glucose" = 0.1 M`
