Chemistry Question on Solutions

1 g of polymer having molar mass 1,60,000 g is dissolved in 800 mL water. Calculate the osmotic pressure in pascal at 27∘^{\circ}C. (R = 8.314 J K−1mole−1)(R \,= \,8.314\, J \,K^{-1}mole^{-1})

A

19.4

B

0.9

C

0.5

D

1.2

Answer

19.4

Explanation

Solution

π=\pi=CRT π=11.6×105×8.314×300800×10−6=19.4Pa\pi=\frac{1}{1.6\times10^{5}}\times\frac{8.314\times300}{800\times10^{-6}}=19.4 Pa
