Question

Calculate the osmotic pressure at `17^(@)C` of an aqueous solution containing `1.75 g` of sucrose per `150 mL` solution.

Answer 1

Given that, `w = 1.75 g`, `m = 342`
`V = (150)/(1000)litre`, `T = 290 K`
`piV = nST = (w)/(m)ST`
`pi xx (150)/(1000) = (1.75)/(342) xx 0.0821 xx 290`
`pi = 0.812 atm`
