The osmotic pressure of solution containing `34.2 g` of cane sugar (molar mass = 342 g `mol^(-1)` ) in 1 L of solution at `20^(@)C` is (Given `R = 0.082` L atm `K^(-1) mol^(-1)` )

Options

A. 2.40 atm
B. 3.6 atm
C. 24 atm
D. 0.0024 atm

Answer

A

Explanation

`pi =CRT `
`pi = ( 34.2 )/( 342 xx 1L ) xx 0.082 xx 293 = 2.40 atm`
