At 10°C, the osmotic pressure of urea solution was formed to be 500 mm. The solution is diluted 'x' times and the temperature raised to 25°C when the osmotic prssure was noticed to be 105.3mm, then 'x' is
I(before dilution) II(after dilution)
= 500mm = 105.3mm
T1 = (10+273)K T2 = (25+273)K
V1 = 1 lit V2 = x lit
the amount of urea remains constant , Wt. and GMW of urea remain constant
x=5
the solution is diluted by 5 times
