Each question contains STATEMENT-I(Assertion) and STATEMENT-2(Reason).the statement carefully and mark the correct answer accoring to the instrution given below: STATEMENT - 1 : The molescular mass of acetic acid determined by depression in freezing point method in benzene and water was found to be differrent. STATEMENT - 2 : Water is polar and benzene is non-polar.
The density of a 2.05 M acetic acid in water is 1.02gcm^-3 . Calculate the molality of the solution.
1g of charcoal adsorbs 1 00mL of 0.6 M CH_3COOH to form a monolayer and thereby molarity of acetic acid is reduced to 0.49 M. Calculate the surface area of the charcoal adsorbed by each molecule of acetic acid. Surface area of charcoal = 3.01 xx10^2 m^2//g
