Question
20 g of a substance were dissolved in 500 mL of water and the osmotic pressure of the solution was found to be 600 mm of mercury at 15oC. The molucular weight of substance is :
Options
A.998
B.1028
C.1098
D.1198
Solution
πV = nRT
× 0.082 ×(273 + 15)
× 0.082 × 288
m =
= 1198
× 0.082 ×(273 + 15)× 0.082 × 288m =
= 1198Create a free account to view solution
