`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`

Text Solution

Verified by Experts

b. `pi V=(n_(1)+n_(2))RT`
`pi V=(W_(1)/(Mw_(1)) + W_(2)/(Mw_(2)))(RT)`
`(pi xx1)=(18/180 + 6/60)xx(0.0821xx300)`
`pi=4.926 atm`
