What is the mole fraction of solute in a 5 ~m aqueous solution?

Step-by-step solution

A 5 m aqueous solution means 5 moles of solute are dissolved in 1 kg ( 1000 g ) of solvent (water). The number of moles of water ( n_ solvent ) is calculated as: n_ solvent = 1000 g 18 g/mol 55.56 mol The mole fraction of the solute ( x_ solute ) is given by the ratio of moles of solute to the total number of moles in the solution: x_ solute = n_ solute n_ solute + n_ solvent x_ solute = 5 5 + 55.56 = 5 60.56 x_ solute 0.08256 Answer: 0.082
