Mass of ethyl=46.07 g/mol. mass solvent =2.50 kg. molality of solution =1.54 mol/kg molality =mol solutes /kg solvent.
1.54 mol/kg =mol solutes /2.50 kg
(2.50kg) (1.54 mol/kg ) =mol solutes 3.85
(3.85 ) (46.07 g /mol) =177.37 g.
Answer is 177 g
1.54 mol/kg =mol solutes /2.50 kg
(2.50kg) (1.54 mol/kg ) =mol solutes 3.85
(3.85 ) (46.07 g /mol) =177.37 g.
Answer is 177 g
