The osmotic pressure of 5% sol of sucrose (M.M = 342) at 150 0 C, is
AnswerClick to flip back
A
5.07 atm
💡 Explanation:
The 5 % sol of sucrose means that 100 cm3 of sol contains 5 g of sucrose.
Here, WB = 5 g, MB = 342 n mol-1, T = 150 + 273 = 423K, V = 0.100L, R = 0.082L atm mol-1K-1$\pi$ = nB/V RT = WBRT/MBRT = 5x0.082x423/342x0.100 = 5.07 atm
