The osmotic pressure of a solution (density is 1 g `mL^(-1))` containing `3 g` of glucose (molecular weight =180) in `60 g` of water at `15^(@)C` is

Options

A. 41.570 kPa
B. 415.70 kPa
C. 41570 kPa
D. 4157 kPa

Answer

C

Explanation

`pi V = nRT`
`pi xx M/d ="Mass"/"Molar Mass" xx R xx T` ltrbgt `d = 1g //mL=1 xx 10^(3) g//L`
` :. pi xx M/(1 xx 10^(3))=W/ "Molar Mass" xx R xx T``pi xx 63/1000 = 3/180 xx 8.314 xx (15 + 273) = 41570 "kPa"`
