Question

`18 g` glucose and `6 g` urea are dissolved in `1 L` aqueous solution at `27^(@)C`. The osmotic pressure of the solution will be
a.`8.826 atm`, b.`4.926 atm`,c.`2.92 atm`, d.`4.42 atm`
A. 3.826 atm
B. 4.926 atm
C. 2.92 atm
D. 9.42 atm

Answer 1

Correct Answer - B
`piV=(n_(1)+n_(2))RT`
`piV=((w_(1))/(m_(1))+(w_(2))/(m_(2)))RT`
`pixx1=((18)/(180)+(6)/(60))xx0.0821xx300`
`pi = 4.926` atm]
