At 27^(@)C temperature, 36 gm glucose is in 1 litre aqueous solution has pi = 4.98 bar. Find out concentration if pi = 1.52 bar at same temperature.

Answer»

Solution :`pi = iCRT = CRT (because i=1" for GLUCOSE")`
`4.98 =(36)/(180)xx RT ""` ….(1)
`pi = C xx RT ""` …..(2)
Now,`("equation (1)")/("equation (2)")=(4.98)/(pi)=(36)/(180)xx(1)/(C )`
`therefore C = 0.061 MOL L^(-1)`
