1.	The molality of a solution of ethyl alcohol in water in 1.55 m. How many grams of ethyl alcohol are dissolved in 2kg of water ?
Answer» Solution :Molarity of solution `= (("MASS of "C_(2)H_(5)OH)/("Molar mass of "C_(2)H_(5)OH))/("Mass of solvent in kg")` `("1.55 mol kg"^(-1))=(W)/(("46 g mol"^(-1))XX(2kg))` `W=("1.55 mol kg"^(-1))xx("46 g mol"^(-1))xx(2kg)=142.6g`.
