Solution of 12 g of non-electrolyte (A) prepared by dissolving it in 1000 mL of water exerts the same osmotic pressure as that of 0 . 05 M glucose solution at the same temperature. The empirical formula of A is CH 2 O . The molecular mass of A is ________g . (Nearest integer)

Correct answer

0

Step-by-step solution

The pressure which applied externally in the solution side to prevent the osmosis process is known as osmotic pressure. It can be denoted by π . Since, ( π 1 ) non   electrolyte   =   ( π 2 ) glucose C 1 RT   =   C 2 RT W 1 M 1 = W 2 M 2 Empirical mass of 12 M 1   =   0 . 05 M 1   =   12 0 . 05   =   240
